BACKGROUND

The global population is predicted to increase to over 9 billion peopleby the year 2050 with a concurrent reduction in the quantity of land,water, and other natural resources available per capita. Projectionsindicate that the average domestic income will also increase, with theprojected rise in the GDP of China and India. The desire for a dietricher in animal-source proteins rises in tandem with increasing income,thus the global livestock sector will be charged with the challenge ofproducing more milk using fewer resources. The Food and AgricultureOrganization of the United Nations predict that 70% more food will haveto be produced, yet the area of arable land available will decrease. Itis clear that the food output per unit of resource input will have toincrease considerably in order to support the rise in population.

Milk and milk components from lactating ruminants are predominantlyutilized in the preparation of foodstuffs in many different forms.Nevertheless, milk and milk components find numerous alternativeapplications in non-food areas such as the manufacture of glues, textilefibers, plastic materials, or in the production of ethanol or methane.There have been many strategies to improve milk production and contentin ruminants through nutritional modulations, hormone treatments,changes in animal management, and selective breeding; however, the needfor more efficient production of milk and milk components per animal isrequired.

Identifying compositions and methods for sustainably increasing milkproduction and modulating milk components of interest while balancinganimal health and wellbeing have become imperative to satisfy the needsof every day humans in an expanding population. Increasing the worldwideproduction of milk and further modulating desirable milk components byscaling up the total number of livestock on dairy farms would not onlybe economically infeasible for many parts of the world, but wouldfurther result in negative environmental consequences.

Thus, meeting global milk and milk component yield expectations, bysimply scaling up current high-input agricultural systems—utilized inmost of the developed world—is simply not feasible.

There is therefore an urgent need in the art for improved methods ofincreasing milk production and further increasing yield of desirablemilk components.

DETAILED DESCRIPTION Definitions

While the following terms are believed to be well understood by one ofordinary skill in the art, the following definitions are set forth tofacilitate explanation of the presently disclosed subject matter.

The term “a” or “an” may refer to one or more of that entity, i.e. canrefer to plural referents. As such, the terms “a” or “an”, “one or more”and “at least one” are used interchangeably herein. In addition,reference to “an element” by the indefinite article “a” or “an” does notexclude the possibility that more than one of the elements is present,unless the context clearly requires that there is one and only one ofthe elements.

Reference throughout this specification to “one embodiment”, “anembodiment”, “one aspect”, or “an aspect” means that a particularfeature, structure or characteristic described in connection with theembodiment is included in at least one embodiment of the presentdisclosure. Thus, the appearances of the phrases “in one embodiment” or“in an embodiment” in various places throughout this specification arenot necessarily all referring to the same embodiment. Furthermore, theparticular features, structures, or characteristics can be combined inany suitable manner in one or more embodiments.

As used herein, in particular embodiments, the terms “about” or“approximately” when preceding a numerical value indicates the valueplus or minus a range of 10%.

As used herein the terms “microorganism” or “microbe” should be takenbroadly. These terms are used interchangeably and include, but are notlimited to, the two prokaryotic domains, Bacteria and Archaea,eukaryotic fungi and protists, as well as viruses. In some embodiments,the disclosure refers to the “microbes” of Table 1 or Table 3, or the“microbes” incorporated by reference. This characterization can refer tonot only the predicted taxonomic microbial identifiers of the table, butalso the identified strains of the microbes listed in the table.

The term “microbial consortia” or “microbial consortium” refers to asubset of a microbial community of individual microbial species, orstrains of a species, which can be described as carrying out a commonfunction, or can be described as participating in, or leading to, orcorrelating with, a recognizable parameter, such as a phenotypic traitof interest (e.g. increased milk production in a ruminant). Thecommunity may comprise two or more species, or strains of a species, ofmicrobes. In some instances, the microbes coexist within the communitysymbiotically.

The term “microbial community” means a group of microbes comprising twoor more species or strains. Unlike microbial consortia, a microbialcommunity does not have to be carrying out a common function, or doesnot have to be participating in, or leading to, or correlating with, arecognizable parameter, such as a phenotypic trait of interest (e.g.increased milk production in a ruminant).

As used herein, “isolate,” “isolated,” “isolated microbe,” and liketerms, are intended to mean that the one or more microorganisms has beenseparated from at least one of the materials with which it is associatedin a particular environment (for example soil, water, animal tissue).

Microbes of the present disclosure may include spores and/or vegetativecells. In some embodiments, microbes of the present disclosure includemicrobes in a viable but non-culturable (VBNC) state. See Liao and Zhao(US Publication US2015267163A1). In some embodiments, microbes of thepresent disclosure include microbes in a biofilm. See Merritt et al.(U.S. Pat. No. 7,427,408).

Thus, an “isolated microbe” does not exist in its naturally occurringenvironment; rather, it is through the various techniques describedherein that the microbe has been removed from its natural setting andplaced into a non-naturally occurring state of existence. Thus, theisolated strain or isolated microbe may exist as, for example, abiologically pure culture, or as spores (or other forms of the strain)in association with an acceptable carrier.

As used herein, “spore” or “spores” refer to structures produced bybacteria and fungi that are adapted for survival and dispersal. Sporesare generally characterized as dormant structures, however spores arecapable of differentiation through the process of germination.Germination is the differentiation of spores into vegetative cells thatare capable of metabolic activity, growth, and reproduction. Thegermination of a single spore results in a single fungal or bacterialvegetative cell. Fungal spores are units of asexual reproduction, and insome cases are necessary structures in fungal life cycles. Bacterialspores are structures for surviving conditions that may ordinarily benonconductive to the survival or growth of vegetative cells.

As used herein, “microbial composition” refers to a compositioncomprising one or more microbes of the present disclosure, wherein amicrobial composition, in some embodiments, is administered to animalsof the present disclosure.

As used herein, “carrier”, “acceptable carrier”, or “pharmaceuticalcarrier” refers to a diluent, adjuvant, excipient, or vehicle with whichthe compound is administered. Such carriers can be sterile liquids, suchas water and oils, including those of petroleum, animal, vegetable, orsynthetic origin; such as peanut oil, soybean oil, mineral oil, sesameoil, and the like. Water or aqueous solution saline solutions andaqueous dextrose and glycerol solutions are preferably employed ascarriers, in some embodiments as injectable solutions. Alternatively,the carrier can be a solid dosage form carrier, including but notlimited to one or more of a binder (for compressed pills), a glidant, anencapsulating agent, a flavorant, and a colorant. The choice of carriercan be selected with regard to the intended route of administration andstandard pharmaceutical practice. See Hardee and Baggo (1998.Development and Formulation of Veterinary Dosage Forms. 2^(nd) Ed. CRCPress. 504 pg.); E. W. Martin (1970. Remington's PharmaceuticalSciences. 17^(th) Ed. Mack Pub. Co.); and Blaser et al. (US PublicationUS20110280840A1).

In certain aspects of the disclosure, the isolated microbes exist asisolated and biologically pure cultures. It will be appreciated by oneof skill in the art, that an isolated and biologically pure culture of aparticular microbe, denotes that said culture is substantially free(within scientific reason) of other living organisms and contains onlythe individual microbe in question. The culture can contain varyingconcentrations of said microbe. The present disclosure notes thatisolated and biologically pure microbes often “necessarily differ fromless pure or impure materials.” See, e.g. In re Bergstrom, 427 F.2d1394, (CCPA 1970) (discussing purified prostaglandins), see also, In reBergy, 596 F.2d 952 (CCPA 1979) (discussing purified microbes), seealso, Parke-Davis & Co. v. H. K. Mulford & Co., 189 F. 95 (S.D.N.Y.1911) (Learned Hand discussing purified adrenaline), aff'd in part,rev'd in part, 196 F. 496 (2d Cir. 1912), each of which are incorporatedherein by reference. Furthermore, in some aspects, the disclosureprovides for certain quantitative measures of the concentration, orpurity limitations, that must be found within an isolated andbiologically pure microbial culture. The presence of these purityvalues, in certain embodiments, is a further attribute thatdistinguishes the presently disclosed microbes from those microbesexisting in a natural state. See, e.g., Merck & Co. v. Olin MathiesonChemical Corp., 253 F.2d 156 (4th Cir. 1958) (discussing puritylimitations for vitamin B12 produced by microbes), incorporated hereinby reference.

As used herein, “individual isolates” should be taken to mean acomposition, or culture, comprising a predominance of a single genera,species, or strain, of microorganism, following separation from one ormore other microorganisms. The phrase should not be taken to indicatethe extent to which the microorganism has been isolated or purified.However, “individual isolates” can comprise substantially only onegenus, species, or strain, of microorganism.

As used herein, “microbiome” refers to the collection of microorganismsthat inhabit the digestive tract or gastrointestinal tract of an animal(including the rumen if said animal is a ruminant) and themicroorgansims' physical environment (i.e. the microbiome has a bioticand physical component). The microbiome is fluid and may be modulated bynumerous naturally occurring and artificial conditions (e.g., change indiet, disease, antimicrobial agents, influx of additionalmicroorganisms, etc.). The modulation of the microbiome of a rumen thatcan be achieved via administration of the compositions of thedisclosure, can take the form of: (a) increasing or decreasing aparticular Family, Genus, Species, or functional grouping of microbe(i.e. alteration of the biotic component of the rumen microbiome) and/or(b) increasing or decreasing volatile fatty acids in the rumen,increasing or decreasing rumen pH, increasing or decreasing any otherphysical parameter important for rumen health (i.e. alteration of theabiotic component of the rumen mircrobiome).

As used herein, “probiotic” refers to a substantially pure microbe(i.e., a single isolate) or a mixture of desired microbes, and may alsoinclude any additional components that can be administered to a mammalfor restoring microbiota. Probiotics or microbial inoculant compositionsof the invention may be administered with an agent to allow the microbesto survive the environment of the gastrointestinal tract, i.e., toresist low pH and to grow in the gastrointestinal environment. In someembodiments, the present compositions (e.g., microbial compositions) areprobiotics in some aspects.

As used herein, “prebiotic” refers to an agent that increases the numberand/or activity of one or more desired microbes. Non-limiting examplesof prebiotics that may be useful in the methods of the presentdisclosure include fructooligosaccharides (e.g., oligofructose, inulin,inulin-type fructans), galactooligosaccharides, amino acids, alcohols,and mixtures thereof. See Ramirez-Farias et al. (2008. Br. J. Nutr.4:1-10) and Pool-Zobel and Sauer (2007. J. Nutr. 137:2580-2584 andsupplemental).

The term “growth medium” as used herein, is any medium which is suitableto support growth of a microbe. By way of example, the media may benatural or artificial including gastrin supplemental agar, LB media,blood serum, and tissue culture gels. It should be appreciated that themedia may be used alone or in combination with one or more other media.It may also be used with or without the addition of exogenous nutrients.

The medium may be amended or enriched with additional compounds orcomponents, for example, a component which may assist in the interactionand/or selection of specific groups of microorganisms. For example,antibiotics (such as penicillin) or sterilants (for example, quaternaryammonium salts and oxidizing agents) could be present and/or thephysical conditions (such as salinity, nutrients (for example organicand inorganic minerals (such as phosphorus, nitrogenous salts, ammonia,potassium and micronutrients such as cobalt and magnesium), pH, and/ortemperature) could be amended.

As used herein, the term “ruminant” includes mammals that are capable ofacquiring nutrients from plant-based food by fermenting it in aspecialized stomach (rumen) prior to digestion, principally throughmicrobial actions. Ruminants included cattle, goats, sheep, giraffes,yaks, deer, antelope, and others.

As used herein, the term “bovid” includes any member of family Bovidae,which include hoofed mammals such as antelope, sheep, goats, and cattle,among others.

As used herein, “energy-corrected milk” or “ECM” represents the amountof energy in milk based upon milk volume, milk fat, and milk protein.ECM adjusts the milk components to 3.5% fat and 3.2% protein, thusequalizing animal performance and allowing for comparison of productionat the individual animal and herd levels over time. An equation used tocalculate ECM, as related to the present disclosure, is:ECM=(0.327×milk pounds)+(12.95×fat pounds)+(7.2×protein pounds)

As used herein, “improved” should be taken broadly to encompassimprovement of a characteristic of interest, as compared to a controlgroup, or as compared to a known average quantity associated with thecharacteristic in question. For example, “improved” milk productionassociated with application of a beneficial microbe, or consortia, ofthe disclosure can be demonstrated by comparing the milk produced by anungulate treated by the microbes taught herein to the milk of anungulate not treated. In the present disclosure, “improved” does notnecessarily demand that the data be statistically significant (i.e.p<0.05); rather, any quantifiable difference demonstrating that onevalue (e.g. the average treatment value) is different from another (e.g.the average control value) can rise to the level of “improved.”

As used herein, “inhibiting and suppressing” and like terms should notbe construed to require complete inhibition or suppression, althoughthis may be desired in some embodiments.

The term “marker” or “unique marker” as used herein is an indicator ofunique microorganism type, microorganism strain or activity of amicroorganism strain. A marker can be measured in biological samples andincludes without limitation, a nucleic acid-based marker such as aribosomal RNA gene, a peptide- or protein-based marker, and/or ametabolite or other small molecule marker.

The term “metabolite” as used herein is an intermediate or product ofmetabolism. A metabolite in one embodiment is a small molecule.Metabolites have various functions, including in fuel, structural,signaling, stimulatory and inhibitory effects on enzymes, as a cofactorto an enzyme, in defense, and in interactions with other organisms (suchas pigments, odorants and pheromones). A primary metabolite is directlyinvolved in normal growth, development and reproduction. A secondarymetabolite is not directly involved in these processes but usually hasan important ecological function. Examples of metabolites include butare not limited to antibiotics and pigments such as resins and terpenes,etc. Some antibiotics use primary metabolites as precursors, such asactinomycin which is created from the primary metabolite, tryptophan.Metabolites, as used herein, include small, hydrophilic carbohydrates;large, hydrophobic lipids and complex natural compounds.

As used herein, the term “genotype” refers to the genetic makeup of anindividual cell, cell culture, tissue, organism, or group of organisms.

As used herein, the term “allele(s)” means any of one or morealternative forms of a gene, all of which alleles relate to at least onetrait or characteristic. In a diploid cell, the two alleles of a givengene occupy corresponding loci on a pair of homologous chromosomes.Since the present disclosure, in embodiments, relates to QTLs, i.e.genomic regions that may comprise one or more genes or regulatorysequences, it is in some instances more accurate to refer to “haplotype”(i.e. an allele of a chromosomal segment) instead of “allele”, however,in those instances, the term “allele” should be understood to comprisethe term “haplotype”. Alleles are considered identical when they expressa similar phenotype. Differences in sequence are possible but notimportant as long as they do not influence phenotype.

As used herein, the term “locus” (loci plural) means a specific place orplaces or a site on a chromosome where for example a gene or geneticmarker is found.

As used herein, the term “genetically linked” refers to two or moretraits that are co-inherited at a high rate during breeding such thatthey are difficult to separate through crossing.

A “recombination” or “recombination event” as used herein refers to achromosomal crossing over or independent assortment. The term“recombinant” refers to an organism having a new genetic makeup arisingas a result of a recombination event.

As used herein, the term “molecular marker” or “genetic marker” refersto an indicator that is used in methods for visualizing differences incharacteristics of nucleic acid sequences. Examples of such indicatorsare restriction fragment length polymorphism (RFLP) markers, amplifiedfragment length polymorphism (AFLP) markers, single nucleotidepolymorphisms (SNPs), insertion mutations, microsatellite markers(SSRs), sequence-characterized amplified regions (SCARs), cleavedamplified polymorphic sequence (CAPS) markers or isozyme markers orcombinations of the markers described herein which defines a specificgenetic and chromosomal location. Markers further include polynucleotidesequences encoding 16S or 18S rRNA, and internal transcribed spacer(ITS) sequences, which are sequences found between small-subunit andlarge-subunit rRNA genes that have proven to be especially useful inelucidating relationships or distinctions among when compared againstone another. Mapping of molecular markers in the vicinity of an alleleis a procedure which can be performed by the average person skilled inmolecular-biological techniques.

The primary structure of major rRNA subunit 16S comprise a particularcombination of conserved, variable, and hypervariable regions thatevolve at different rates and enable the resolution of both very ancientlineages such as domains, and more modern lineages such as genera. Thesecondary structure of the 16S subunit include approximately 50 heliceswhich result in base pairing of about 67% of the residues. These highlyconserved secondary structural features are of great functionalimportance and can be used to ensure positional homology in multiplesequence alignments and phylogenetic analysis. Over the previous fewdecades, the 16S rRNA gene has become the most sequenced taxonomicmarker and is the cornerstone for the current systematic classificationof bacteria and archaea (Yarza et al. 2014. Nature Rev. Micro.12:635-45).

A sequence identity of 94.5% or lower for two 16S rRNA genes is strongevidence for distinct genera, 86.5% or lower is strong evidence fordistinct families, 82% or lower is strong evidence for distinct orders,78.5% is strong evidence for distinct classes, and 75% or lower isstrong evidence for distinct phyla. The comparative analysis of 16S rRNAgene sequences enables the establishment of taxonomic thresholds thatare useful not only for the classification of cultured microorganismsbut also for the classification of the many environmental sequences.Yarza et al. 2014. Nature Rev. Micro. 12:635-45).

As used herein, the term “trait” refers to a characteristic orphenotype. For example, in the context of some embodiments of thepresent disclosure, quantity of milk fat produced relates to the amountof triglycerides, triacylglycerides, diacylglycerides,monoacylglycerides, phospholipids, cholesterol, glycolipids, and fattyacids present in milk. Desirable traits may also include other milkcharacteristics, including but not limited to: predominance of shortchain fatty acids, medium chain fatty acids, and long chain fatty acids;quantity of carbohydrates such as lactose, glucose, galactose, and otheroligosaccharides; quantity of proteins such as caseins and whey;quantity of vitamins, minerals, milk yield/volume; reductions in methaneemissions or manure; improved efficiency of nitrogen utilization;improved dry matter intake; improved feed efficiency and digestibility;increased degradation of cellulose, lignin, and hemicellulose; increasedrumen concentrations of fatty acids such as acetic acid, propionic acid,and butyric acid; etc.

A trait may be inherited in a dominant or recessive manner, or in apartial or incomplete-dominant manner. A trait may be monogenic (i.e.determined by a single locus) or polygenic (i.e. determined by more thanone locus) or may also result from the interaction of one or more geneswith the environment.

In the context of this disclosure, traits may also result from theinteraction of one or more mammalian genes and one or more microorganismgenes.

As used herein, the term “homozygous” means a genetic condition existingwhen two identical alleles reside at a specific locus, but arepositioned individually on corresponding pairs of homologous chromosomesin the cell of a diploid organism. Conversely, as used herein, the term“heterozygous” means a genetic condition existing when two differentalleles reside at a specific locus, but are positioned individually oncorresponding pairs of homologous chromosomes in the cell of a diploidorganism.

As used herein, the term “phenotype” refers to the observablecharacteristics of an individual cell, cell culture, organism (e.g., aruminant), or group of organisms which results from the interactionbetween that individual's genetic makeup (i.e., genotype) and theenvironment.

As used herein, the term “chimeric” or “recombinant” when describing anucleic acid sequence or a protein sequence refers to a nucleic acid, ora protein sequence, that links at least two heterologouspolynucleotides, or two heterologous polypeptides, into a singlemacromolecule, or that re-arranges one or more elements of at least onenatural nucleic acid or protein sequence. For example, the term“recombinant” can refer to an artificial combination of two otherwiseseparated segments of sequence, e.g., by chemical synthesis or by themanipulation of isolated segments of nucleic acids by geneticengineering techniques.

As used herein, a “synthetic nucleotide sequence” or “syntheticpolynucleotide sequence” is a nucleotide sequence that is not known tooccur in nature or that is not naturally occurring. Generally, such asynthetic nucleotide sequence will comprise at least one nucleotidedifference when compared to any other naturally occurring nucleotidesequence.

As used herein, the term “nucleic acid” refers to a polymeric form ofnucleotides of any length, either ribonucleotides ordeoxyribonucleotides, or analogs thereof. This term refers to theprimary structure of the molecule, and thus includes double- andsingle-stranded DNA, as well as double- and single-stranded RNA. It alsoincludes modified nucleic acids such as methylated and/or capped nucleicacids, nucleic acids containing modified bases, backbone modifications,and the like. The terms “nucleic acid” and “nucleotide sequence” areused interchangeably.

As used herein, the term “gene” refers to any segment of DNA associatedwith a biological function. Thus, genes include, but are not limited to,coding sequences and/or the regulatory sequences required for theirexpression. Genes can also include non-expressed DNA segments that, forexample, form recognition sequences for other proteins. Genes can beobtained from a variety of sources, including cloning from a source ofinterest or synthesizing from known or predicted sequence information,and may include sequences designed to have desired parameters.

As used herein, the term “homologous” or “homologue” or “ortholog” isknown in the art and refers to related sequences that share a commonancestor or family member and are determined based on the degree ofsequence identity. The terms “homology,” “homologous,” “substantiallysimilar” and “corresponding substantially” are used interchangeablyherein. They refer to nucleic acid fragments wherein changes in one ormore nucleotide bases do not affect the ability of the nucleic acidfragment to mediate gene expression or produce a certain phenotype.These terms also refer to modifications of the nucleic acid fragments ofthe instant disclosure such as deletion or insertion of one or morenucleotides that do not substantially alter the functional properties ofthe resulting nucleic acid fragment relative to the initial, unmodifiedfragment. It is therefore understood, as those skilled in the art willappreciate, that the disclosure encompasses more than the specificexemplary sequences. These terms describe the relationship between agene found in one species, subspecies, variety, cultivar or strain andthe corresponding or equivalent gene in another species, subspecies,variety, cultivar or strain. For purposes of this disclosure homologoussequences are compared. “Homologous sequences” or “homologues” or“orthologs” are thought, believed, or known to be functionally related.A functional relationship may be indicated in any one of a number ofways, including, but not limited to: (a) degree of sequence identityand/or (b) the same or similar biological function. Preferably, both (a)and (b) are indicated. Homology can be determined using softwareprograms readily available in the art, such as those discussed inCurrent Protocols in Molecular Biology (F. M. Ausubel et al., eds.,1987) Supplement 30, section 7.718, Table 7.71. Some alignment programsare MacVector (Oxford Molecular Ltd, Oxford, U.K.), ALIGN Plus(Scientific and Educational Software, Pennsylvania) and AlignX (VectorNTI, Invitrogen, Carlsbad, Calif.). Another alignment program isSequencher (Gene Codes, Ann Arbor, Mich.), using default parameters.

As used herein, the term “nucleotide change” refers to, e.g., nucleotidesubstitution, deletion, and/or insertion, as is well understood in theart. For example, mutations contain alterations that produce silentsubstitutions, additions, or deletions, but do not alter the propertiesor activities of the encoded protein or how the proteins are made.

As used herein, the term “protein modification” refers to, e.g., aminoacid substitution, amino acid modification, deletion, and/or insertion,as is well understood in the art.

As used herein, the term “at least a portion” or “fragment” of a nucleicacid or polypeptide means a portion having the minimal sizecharacteristics of such sequences, or any larger fragment of the fulllength molecule, up to and including the full length molecule. Afragment of a polynucleotide of the disclosure may encode a biologicallyactive portion of a genetic regulatory element. A biologically activeportion of a genetic regulatory element can be prepared by isolating aportion of one of the polynucleotides of the disclosure that comprisesthe genetic regulatory element and assessing activity as describedherein. Similarly, a portion of a polypeptide may be 4 amino acids, 5amino acids, 6 amino acids, 7 amino acids, and so on, going up to thefull length polypeptide. The length of the portion to be used willdepend on the particular application. A portion of a nucleic acid usefulas a hybridization probe may be as short as 12 nucleotides; in someembodiments, it is 20 nucleotides. A portion of a polypeptide useful asan epitope may be as short as 4 amino acids. A portion of a polypeptidethat performs the function of the full-length polypeptide wouldgenerally be longer than 4 amino acids.

Variant polynucleotides also encompass sequences derived from amutagenic and recombinogenic procedure such as DNA shuffling. Strategiesfor such DNA shuffling are known in the art. See, for example, Stemmer(1994) PNAS 91:10747-10751; Stemmer (1994) Nature 370:389-391; Crameriet al. (1997) Nature Biotech. 15:436-438; Moore et al. (1997) J. Mol.Biol. 272:336-347; Zhang et al. (1997) PNAS 94:4504-4509; Crameri et al.(1998) Nature 391:288-291; and U.S. Pat. Nos. 5,605,793 and 5,837,458.For PCR amplifications of the polynucleotides disclosed herein,oligonucleotide primers can be designed for use in PCR reactions toamplify corresponding DNA sequences from cDNA or genomic DNA extractedfrom any organism of interest. Methods for designing PCR primers and PCRcloning are generally known in the art and are disclosed in Sambrook etal. (1989) Molecular Cloning: A Laboratory Manual (2nd ed., Cold SpringHarbor Laboratory Press, Plainview, N.Y.). See also Innis et al., eds.(1990) PCR Protocols: A Guide to Methods and Applications (AcademicPress, New York); Innis and Gelfand, eds. (1995) PCR Strategies(Academic Press, New York); and Innis and Gelfand, eds. (1999) PCRMethods Manual (Academic Press, New York). Known methods of PCR include,but are not limited to, methods using paired primers, nested primers,single specific primers, degenerate primers, gene-specific primers,vector-specific primers, partially-mismatched primers, and the like.

The term “primer” as used herein refers to an oligonucleotide which iscapable of annealing to the amplification target allowing a DNApolymerase to attach, thereby serving as a point of initiation of DNAsynthesis when placed under conditions in which synthesis of primerextension product is induced, i.e., in the presence of nucleotides andan agent for polymerization such as DNA polymerase and at a suitabletemperature and pH. The (amplification) primer is preferably singlestranded for maximum efficiency in amplification. Preferably, the primeris an oligodeoxyribonucleotide. The primer must be sufficiently long toprime the synthesis of extension products in the presence of the agentfor polymerization. The exact lengths of the primers will depend on manyfactors, including temperature and composition (A/T vs. G/C content) ofprimer. A pair of bi-directional primers consists of one forward and onereverse primer as commonly used in the art of DNA amplification such asin PCR amplification.

The terms “stringency” or “stringent hybridization conditions” refer tohybridization conditions that affect the stability of hybrids, e.g.,temperature, salt concentration, pH, formamide concentration and thelike. These conditions are empirically optimized to maximize specificbinding and minimize non-specific binding of primer or probe to itstarget nucleic acid sequence. The terms as used include reference toconditions under which a probe or primer will hybridize to its targetsequence, to a detectably greater degree than other sequences (e.g. atleast 2-fold over background). Stringent conditions are sequencedependent and will be different in different circumstances. Longersequences hybridize specifically at higher temperatures. Generally,stringent conditions are selected to be about 5° C. lower than thethermal melting point (Tm) for the specific sequence at a defined ionicstrength and pH. The Tm is the temperature (under defined ionic strengthand pH) at which 50% of a complementary target sequence hybridizes to aperfectly matched probe or primer. Typically, stringent conditions willbe those in which the salt concentration is less than about 1.0 M Na+ion, typically about 0.01 to 1.0 M Na+ ion concentration (or othersalts) at pH 7.0 to 8.3 and the temperature is at least about 30° C. forshort probes or primers (e.g. 10 to 50 nucleotides) and at least about60° C. for long probes or primers (e.g. greater than 50 nucleotides).Stringent conditions may also be achieved with the addition ofdestabilizing agents such as formamide. Exemplary low stringentconditions or “conditions of reduced stringency” include hybridizationwith a buffer solution of 30% formamide, 1 M NaCl, 1% SDS at 37° C. anda wash in 2×SSC at 40° C. Exemplary high stringency conditions includehybridization in 50% formamide, 1M NaCl, 1% SDS at 37° C., and a wash in0.1×SSC at 60° C. Hybridization procedures are well known in the art andare described by e.g. Ausubel et al., 1998 and Sambrook et al., 2001. Insome embodiments, stringent conditions are hybridization in 0.25 MNa2HPO4 buffer (pH 7.2) containing 1 mM Na2EDTA, 0.5-20% sodium dodecylsulfate at 45° C., such as 0.5%, 1%, 2%, 3%, 4%, 5%, 6%, 7%, 8%, 9%,10%, 11%, 12%, 13%, 14%, 15%, 16%, 17%, 18%, 19% or 20%, followed by awash in 5×SSC, containing 0.1% (w/v) sodium dodecyl sulfate, at 55° C.to 65° C.

As used herein, “promoter” refers to a DNA sequence capable ofcontrolling the expression of a coding sequence or functional RNA. Thepromoter sequence consists of proximal and more distal upstreamelements, the latter elements often referred to as enhancers.Accordingly, an “enhancer” is a DNA sequence that can stimulate promoteractivity, and may be an innate element of the promoter or a heterologouselement inserted to enhance the level or tissue specificity of apromoter. Promoters may be derived in their entirety from a native gene,or be composed of different elements derived from different promotersfound in nature, or even comprise synthetic DNA segments. It isunderstood by those skilled in the art that different promoters maydirect the expression of a gene in different tissues or cell types, orat different stages of development, or in response to differentenvironmental conditions. It is further recognized that since in mostcases the exact boundaries of regulatory sequences have not beencompletely defined, DNA fragments of some variation may have identicalpromoter activity.

As used herein, a “constitutive promoter” is a promoter which is activeunder most conditions and/or during most development stages. There areseveral advantages to using constitutive promoters in expression vectorsused in biotechnology, such as: high level of production of proteinsused to select transgenic cells or organisms; high level of expressionof reporter proteins or scorable markers, allowing easy detection andquantification; high level of production of a transcription factor thatis part of a regulatory transcription system; production of compoundsthat requires ubiquitous activity in the organism; and production ofcompounds that are required during all stages of development.Non-limiting exemplary constitutive promoters include, CaMV 35Spromoter, opine promoters, ubiquitin promoter, alcohol dehydrogenasepromoter, etc.

As used herein, a “non-constitutive promoter” is a promoter which isactive under certain conditions, in certain types of cells, and/orduring certain development stages. For example, tissue specific, tissuepreferred, cell type specific, cell type preferred, inducible promoters,and promoters under development control are non-constitutive promoters.Examples of promoters under developmental control include promoters thatpreferentially initiate transcription in certain tissues.

As used herein, “inducible” or “repressible” promoter is a promoterwhich is under chemical or environmental factors control. Examples ofenvironmental conditions that may affect transcription by induciblepromoters include anaerobic conditions, certain chemicals, the presenceof light, acidic or basic conditions, etc.

As used herein, a “tissue specific” promoter is a promoter thatinitiates transcription only in certain tissues. Unlike constitutiveexpression of genes, tissue-specific expression is the result of severalinteracting levels of gene regulation. As such, in the art sometimes itis preferable to use promoters from homologous or closely relatedspecies to achieve efficient and reliable expression of transgenes inparticular tissues. This is one of the main reasons for the large amountof tissue-specific promoters isolated from particular tissues found inboth scientific and patent literature.

As used herein, the term “operably linked” refers to the association ofnucleic acid sequences on a single nucleic acid fragment so that thefunction of one is regulated by the other. For example, a promoter isoperably linked with a coding sequence when it is capable of regulatingthe expression of that coding sequence (i.e., that the coding sequenceis under the transcriptional control of the promoter). Coding sequencescan be operably linked to regulatory sequences in a sense or antisenseorientation. In another example, the complementary RNA regions of thedisclosure can be operably linked, either directly or indirectly, 5′ tothe target mRNA, or 3′ to the target mRNA, or within the target mRNA, ora first complementary region is 5′ and its complement is 3′ to thetarget mRNA.

As used herein, the phrases “recombinant construct”, “expressionconstruct”, “chimeric construct”, “construct”, and “recombinant DNAconstruct” are used interchangeably herein. A recombinant constructcomprises an artificial combination of nucleic acid fragments, e.g.,regulatory and coding sequences that are not found together in nature.For example, a chimeric construct may comprise regulatory sequences andcoding sequences that are derived from different sources, or regulatorysequences and coding sequences derived from the same source, butarranged in a manner different than that found in nature. Such constructmay be used by itself or may be used in conjunction with a vector. If avector is used then the choice of vector is dependent upon the methodthat will be used to transform host cells as is well known to thoseskilled in the art. For example, a plasmid vector can be used. Theskilled artisan is well aware of the genetic elements that must bepresent on the vector in order to successfully transform, select andpropagate host cells comprising any of the isolated nucleic acidfragments of the disclosure. The skilled artisan will also recognizethat different independent transformation events will result indifferent levels and patterns of expression (Jones et al., (1985) EMBOJ. 4:2411-2418; De Almeida et al., (1989) Mol. Gen. Genetics 218:78-86),and thus that multiple events must be screened in order to obtain linesdisplaying the desired expression level and pattern. Such screening maybe accomplished by Southern analysis of DNA, Northern analysis of mRNAexpression, immunoblotting analysis of protein expression, or phenotypicanalysis, among others. Vectors can be plasmids, viruses,bacteriophages, pro-viruses, phagemids, transposons, artificialchromosomes, and the like, that replicate autonomously or can integrateinto a chromosome of a host cell. A vector can also be a naked RNApolynucleotide, a naked DNA polynucleotide, a polynucleotide composed ofboth DNA and RNA within the same strand, a poly-lysine-conjugated DNA orRNA, a peptide-conjugated DNA or RNA, a liposome-conjugated DNA, or thelike, that is not autonomously replicating. As used herein, the term“expression” refers to the production of a functional end-product e.g.,an mRNA or a protein (precursor or mature).

In some embodiments, the cell or organism has at least one heterologoustrait. As used herein, the term “heterologous trait” refers to aphenotype imparted to a transformed host cell or transgenic organism byan exogenous DNA segment, heterologous polynucleotide or heterologousnucleic acid. Various changes in phenotype are of interest to thepresent disclosure, including but not limited to modifying the fattyacid composition in milk, altering the carbohydrate content of milk,increasing an ungulate's yield of an economically important trait (e.g.,milk, milk fat, milk proteins, etc.) and the like. These results can beachieved by providing expression of heterologous products or increasedexpression of endogenous products in organisms using the methods andcompositions of the present disclosure.

As used herein, the term “MIC” means maximal information coefficient.MIC is a type of nonparamentric network analysis that identifies a score(MIC score) between active microbial strains of the present disclosureand at least one measured metadata (e.g., milk fat). Further, U.S.application Ser. No. 15/217,575, filed on Jul. 22, 2016 (issued as U.S.Pat. No. 9,540,676 on Jan. 10, 2017) is hereby incorporated by referencein its entirety.

The maximal information coefficient (MIC) is then calculated betweenstrains and metadata 3021 a, and between strains 3021 b; as seen in FIG.17. Results are pooled to create a list of all relationships and theircorresponding MIC scores 3022. If the relationship scores below a giventhreshold 3023, the relationship is deemed/identified as irrelevant 3023b. If the relationship is above a given threshold 3023, the relationshipdeemed/identified as relevant 2023 a, and is further subject to networkanalysis 3024. The following code fragment shows an exemplarymethodology for such analysis, according to one embodiment:

for i in range(len(links)):

-   -   if links >=threshold        -   multiplier[i]=1    -   else        -   multiplier[i]=0    -   end if

links_temp=multiplier*links

final_links=links_temp[links_temp !=0]

Based on the output of the network analysis, active strains are selected3025 for preparing products (e.g., ensembles, aggregates, and/or othersynthetic groupings) containing the selected strains. The output of thenetwork analysis can also be used to inform the selection of strains forfurther product composition testing.

The use of thresholds is discussed above for analyses anddeterminations. Thresholds can be, depending on the implementation andapplication: (1) empirically determined (e.g., based on distributionlevels, setting a cutoff at a number that removes a specified orsignificant portion of low level reads); (2) any non-zero value; (3)percentage/percentile based; (4) only strains whose normalized secondmarker (i.e., activity) reads is greater than normalized first marker(cell count) reads; (5) log 2 fold change between activity and quantityor cell count; (6) normalized second marker (activity) reads is greaterthan mean second marker (activity) reads for entire sample (and/orsample set); and/or any magnitude threshold described above in additionto a statistical threshold (i.e., significance testing). The followingexample provides thresholding detail for distributions of RNA-basedsecond marker measurements with respect to DNA-based first markermeasurements, according to one embodiment.

As used herein “shelf-stable” refers to a functional attribute and newutility acquired by the microbes formulated according to the disclosure,which enable said microbes to exist in a useful/active state outside oftheir natural environment in the rumen (i.e. a markedly differentcharacteristic). Thus, shelf-stable is a functional attribute created bythe formulations/compositions of the disclosure and denoting that themicrobe formulated into a shelf-stable composition can exist outside therumen and under ambient conditions for a period of time that can bedetermined depending upon the particular formulation utilized, but ingeneral means that the microbes can be formulated to exist in acomposition that is stable under ambient conditions for at least a fewdays and generally at least one week. Accordingly, a “shelf-stableruminant supplement” is a composition comprising one or more microbes ofthe disclosure, said microbes formulated in a composition, such that thecomposition is stable under ambient conditions for at least one week,meaning that the microbes comprised in the composition (e.g. whole cell,spore, or lysed cell) are able to impart one or more beneficialphenotypic properties to a ruminant when administered (e.g. increasedmilk yield, improved milk compositional characteristics, improved rumenhealth, and/or modulation of the rumen microbiome).

Isolated Microbes—Source Material

The microbes of the present disclosure were obtained, among otherplaces, at various locales in the United States from thegastrointestinal tract of cows.

Isolated Microbes—Microbial Culture Techniques

The microbes of Table 1 and Table 3 were matched to their nearesttaxonomic groups by utilizing classification tools of the RibosomalDatabase Project (RDP) for 16s rRNA sequences and the User-friendlyNordic ITS Ectomycorrhiza (UNITE) database for ITS rRNA sequences.Examples of matching microbes to their nearest taxa may be found in Lanet al. (2012. PLOS one. 7(3):e32491), Schloss and Westcott (2011. Appl.Environ. Microbiol. 77(10):3219-3226), and Koljalg et al. (2005. NewPhytologist. 166(3): 1063-1068).

The isolation, identification, and culturing of the microbes of thepresent disclosure can be effected using standard microbiologicaltechniques. Examples of such techniques may be found in Gerhardt, P.(ed.) Methods for General and Molecular Microbiology. American Societyfor Microbiology, Washington, D.C. (1994) and Lennette, E. H.

Isolation can be effected by streaking the specimen on a solid medium(e.g., nutrient agar plates) to obtain a single colony, which ischaracterized by the phenotypic traits described hereinabove (e.g., Grampositive/negative, capable of forming spores aerobically/anaerobically,cellular morphology, carbon source metabolism, acid/base production,enzyme secretion, metabolic secretions, etc.) and to reduce thelikelihood of working with a culture which has become contaminated.

For example, for microbes of the disclosure, biologically pure isolatescan be obtained through repeated subculture of biological samples, eachsubculture followed by streaking onto solid media to obtain individualcolonies or colony forming units. Methods of preparing, thawing, andgrowing lyophilized bacteria are commonly known, for example, Gherna, R.L. and C. A. Reddy. 2007. Culture Preservation, p 1019-1033. In C. A.Reddy, T. J. Beveridge, J. A. Breznak, G. A. Marzluf, T. M. Schmidt, andL. R. Snyder, eds. American Society for Microbiology, Washington, D.C.,1033 pages; herein incorporated by reference. Thus freeze dried liquidformulations and cultures stored long term at −70° C. in solutionscontaining glycerol are contemplated for use in providing formulationsof the present disclosure.

The microbes of the disclosure can be propagated in a liquid mediumunder aerobic conditions, or alternatively anaerobic conditions.

In someaspects, microbial multi-strain cultures may be obtained by propagatingtwo or more of the strains described hereinabove. It will be appreciatedthat the microbial strains may be cultured together when compatibleculture conditions can be employed.

Isolated Microbes—Microbial Strains

Microbes can be distinguished into a genus based on polyphasic taxonomy,which incorporates all available phenotypic and genotypic data into aconsensus classification (Vandamme et al. 1996. Polyphasic taxonomy, aconsensus approach to bacterial systematics. Microbial Rev 1996,60:407-438). One accepted genotypic method for defining species is basedon overall genomic relatedness, such that strains which shareapproximately 70% or more relatedness using DNA-DNA hybridization, with5° C. or less ΔT_(m) (the difference in the melting temperature betweenhomologous and heterologous hybrids), under standard conditions, areconsidered to be members of the same species. Thus, populations thatshare greater than the aforementioned 70% threshold can be considered tobe variants of the same species. Another accepted genotypic method fordefining species is to isolate marker genes of the present disclosure,sequence these genes, and align these sequenced genes from multipleisolates or variants. The microbes are interpreted as belonging to thesame species if one or more of the sequenced genes share at least 97%sequence identity.

The 16S or 18S rRNA sequences or ITS sequences are often used for makingdistinctions between species and strains, in that if one of theaforementioned sequences share less than a specified percent sequenceidentity from a reference sequence, then the two organisms from whichthe sequences were obtained are said to be of different species orstrains.

Thus, one could consider microbes to be of the same species, if theyshare at least 80%, 85%, 90%, 95%, 97%, 98%, or 99% sequence identityacross the 16S or 18S rRNA sequence, or the ITS1 or ITS2 sequence.

Further, one could define microbial strains of a species, as those thatshare at least 80%, 85%, 90%, 95%, 97%, 98%, or 99% sequence identityacross the 16S or 18S rRNA sequence, or the ITS1 or ITS2 sequence.

In one embodiment, microbial strains of the present disclosure includethose that comprise polynucleotide sequences that share at least 70%,75%, 80%, 81%, 82%, 83%, 84%, 85%, 86%, 87%, 88%, 89%, 90%, 91%, 92%,93%, 94%, 95%, 96%, 97%, 98%, 99% or 100% sequence identity with any oneof SEQ ID NOs:1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17,18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 39, 30, 31, 32, 33, 34, 35,36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 47, 48, 49, 50, 51, 52, 53,54, 55, 56, 57, 58, 59, 60, 2045, 2046, 2047, 2048, 2049, 2050, 2051,2052, 2053, 2054, 2055, 2056, 2057, 2058, 2059, 2060, 2061, 2062, 2063,2064, 2065, 2066, 2067, 2068, 2069, 2070, 2071, 2072, 2073, 2074, 2075,2076, 2077, 2078, 2079, 2080, 2081, 2082, 2083, 2084, 2085, 2086, 2087,2088, 2089, 2090, 2091, 2092, 2093, 2094, 2095, 2096, 2097, 2098, 2099,2100, 2101, 2102, 2103, 2104, 2105, 2106, and 2107. In a furtherembodiment, microbial strains of the present disclosure include thosethat comprise polynucleotide sequences that share at least 70%, 75%,80%, 81%, 82%, 83%, 84%, 85%, 86%, 87%, 88%, 89%, 90%, 91%, 92%, 93%,94%, 95%, 96%, 97%, 98%, 99% or 100% sequence identity with any one ofSEQ ID NOs:1-2107.

Comparisons may also be made with 23S rRNA sequences against referencesequences.

Unculturable microbes often cannot be assigned to a definite species inthe absence of a phenotype determination, the microbes can be given acandidatus designation within a genus provided their 16S or 18S rRNAsequences or ITS sequences subscribes to the principles of identity withknown species.

One approach is to observe the distribution of a large number of strainsof closely related species in sequence space and to identify clusters ofstrains that are well resolved from other clusters. This approach hasbeen developed by using the concatenated sequences of multiple core(house-keeping) genes to assess clustering patterns, and has been calledmultilocus sequence analysis (MLSA) or multilocus sequence phylogeneticanalysis. MLSA has been used successfully to explore clustering patternsamong large numbers of strains assigned to very closely related speciesby current taxonomic methods, to look at the relationships between smallnumbers of strains within a genus, or within a broader taxonomicgrouping, and to address specific taxonomic questions. More generally,the method can be used to ask whether bacterial species exist—that is,to observe whether large populations of similar strains invariably fallinto well-resolved clusters, or whether in some cases there is a geneticcontinuum in which clear separation into clusters is not observed.

In order to more accurately make a determination of genera, adetermination of phenotypic traits, such as morphological, biochemical,and physiological characteristics are made for comparison with areference genus archetype. The colony morphology can include color,shape, pigmentation, production of slime, etc. Features of the cell aredescribed as to shape, size, Gram reaction, extracellular material,presence of endospores, flagella presence and location, motility, andinclusion bodies. Biochemical and physiological features describe growthof the organism at different ranges of temperature, pH, salinity andatmospheric conditions, growth in presence of different sole carbon andnitrogen sources. One of ordinary skill in the art would be reasonablyapprised as to the phenotypic traits that define the genera of thepresent disclosure.

In one embodiment, the microbes taught herein were identified utilizing16S rRNA gene sequences and ITS sequences. It is known in the art that16S rRNA contains hypervariable regions that can providespecies/strain-specific signature sequences useful for bacterialidentification, and that ITS sequences can also providespecies/strain-specific signature sequences useful for fungalidentification.

Phylogenetic analysis using the rRNA genes and/or ITS sequences are usedto define “substantially similar” species belonging to common genera andalso to define “substantially similar” strains of a given taxonomicspecies. Furthermore, physiological and/or biochemical properties of theisolates can be utilized to highlight both minor and significantdifferences between strains that could lead to advantageous behavior inruminants.

In some embodiments, the microbial compositions of the presentdisclosure are shelf stable at any of the disclosed temperatures and/ortemperature ranges and spans of time at a relative humidity of at least1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20,21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38,39, 40, 41, 42, 43, 44, 45, 46, 47, 48, 49, 50, 51, 52, 53, 54, 55, 56,57, 58, 59, 60, 61, 62, 63, 64, 65, 66, 67, 68, 69, 70, 71, 72, 73, 74,75, 76, 77, 78, 79, 80, 81, 82, 83, 84, 85, 86, 87, 88, 89, 90, 91, 92,93, 94, 95, 96, 97, or 98%

Several drying methods can be employed, including, but not limited to,air drying at ambient temperature, spray drying, fluidized bed drying,vacuum drying, and freeze drying. As used herein, the glass containingthe dried bacteria cells preferably contains a residual moisture contentof less than about 5%, and, more preferably, less than about 2%.

Drying is preferably performed under vacuum in a freeze drier at aproduct temperature above the freezing temperature of water under suchconditions. In general, vacuum drying are performed in two stages. Thefirst stage involves moderately reduced pressure (ca. 2500 mTOR) at mildtemperatures (20° C.), while the second stage involves lower pressures(i.e., higher vacuum—100 mTOR) at higher temperature (up to about 50°C.). This process can be achieved using a programmable control systemfor vacuum pressure and product temperature. The vacuum and temperatureconditions for the first drying stage are adjusted empirically accordingthe size of the drier, heat transfer capacity, and the product load, butthe goal is to keep the product above its freezing temperature whilemaximizing the water evaporation rate. In one embodiment, thetemperature is initially maintained at about 20° C. for about 16 hours,followed by gradually increasing the temperature to about 50° C. for thefollowing 48 hours. These drying conditions allow the formation ofglassy state wherein the bacteria are locked in a quiescent state insidethe polysaccharide matrix.

A glass is an amorphous solid state that is obtained by controlleddesiccation of a solution. The advantage of the glassy phase inachieving long term stability results from the fact that diffusion inglassy (vitrified) materials occurs at extremely low rates (e.g.,microbes/year). Glassy materials normally appear as homogeneous,transparent, brittle solids, which can be ground or milled into apowder. The optimal benefits of vitrification for long-term storage areobserved under conditions where Tg is greater than the storagetemperature. The Tg is directly dependent on water activity andtemperature, and may be modified by selecting an appropriate combinationof solutes (i.e., polysaccharides, sugars, salts and proteins).

“Vitrification” (i.e., glass formation) means formation of a glassy ornoncrystalline amorphous material. As used herein the term glass orglassy state means a liquid phase of such high viscosity and low watercontent that all chemical reactions are slowed to a near standstill, andthe bacteria cells become quiescent.

Encapsulation Compositions

In some embodiments, the microbes or microbial compositions of thedisclosure are encapsulated in an encapsulating composition. Anencapsulating composition protects the microbes from external stressorsprior to entering the gastrointestinal tract of ungulates. Encapsulatingcompositions further create an environment that may be beneficial to themicrobes, such as minimizing the oxidative stresses of an aerobicenvironment on anaerobic microbes. See Kalsta et al. (U.S. Pat. No.5,104,662A), Ford (U.S. Pat. No. 5,733,568A), and Mosbach and Nilsson(U.S. Pat. No. 4,647,536A) for encapsulation compositions of microbes,and methods of encapsulating microbes.

In one embodiment, the encapsulating composition comprises microcapsuleshaving a multiplicity of liquid cores encapsulated in a solid shellmaterial. For purposes of the disclosure, a “multiplicity” of cores isdefined as two or more.

A first category of useful fusible shell materials is that of normallysolid fats, including fats which are already of suitable hardness andanimal or vegetable fats and oils which are hydrogenated until theirmelting points are sufficiently high to serve the purposes of thepresent disclosure. Depending on the desired process and storagetemperatures and the specific material selected, a particular fat can beeither a normally solid or normally liquid material. The terms “normallysolid” and “normally liquid” as used herein refer to the state of amaterial at desired temperatures for storing the resultingmicrocapsules. Since fats and hydrogenated oils do not, strictlyspeaking, have melting points, the term “melting point” is used hereinto describe the minimum temperature at which the fusible materialbecomes sufficiently softened or liquid to be successfully emulsifiedand spray cooled, thus roughly corresponding to the maximum temperatureat which the shell material has sufficient integrity to prevent releaseof the choline cores. “Melting point” is similarly defined herein forother materials which do not have a sharp melting point.

Specific examples of fats and oils useful herein (some of which requirehardening) are as follows: animal oils and fats, such as beef tallow,mutton tallow, lamb tallow, lard or pork fat, fish oil, and sperm oil;vegetable oils, such as canola oil, cottonseed oil, peanut oil, cornoil, olive oil, soybean oil, sunflower oil, safflower oil, coconut oil,palm oil, linseed oil, tung oil, and castor oil; fatty acidmonoglycerides and diglycerides; free fatty acids, such as stearic acid,palmitic acid, and oleic acid; and mixtures thereof. The above listingof oils and fats is not meant to be exhaustive, but only exemplary.

Specific examples of fatty acids include linoleic acid, γ-linoleic acid,dihomo-γ-linolenic acid, arachidonic acid, docosatetraenoic acid,vaccenic acid, nervonic acid, mead acid, erucic acid, gondoic acid,elaidic acid, oleic acid, palitoleic acid, stearidonic acid,eicosapentaenoic acid, valeric acid, caproic acid, enanthic acid,caprylic acid, pelargonic acid, capric acid, undecylic acid, lauricacid, tridecylic acid, myristic acid, pentadecylic acid, palmitic acid,margaric acid, stearic acid, nonadecyclic acid, arachidic acid,heneicosylic acid, behenic acid, tricosylic acid, lignoceric acid,pentacosylic acid, cerotic acid, heptacosylic acid, montanic acid,nonacosylic acid, melissic acid, henatriacontylic acid, lacceroic acid,psyllic acid, geddic acid, ceroplastic acid, hexatriacontylic acid,heptatriacontanoic acid, and octatriacontanoic acid.

Another category of fusible materials useful as encapsulating shellmaterials is that of waxes. Representative waxes contemplated for useherein are as follows: animal waxes, such as beeswax, lanolin, shellwax, and Chinese insect wax; vegetable waxes, such as carnauba,candelilla, bayberry, and sugar cane; mineral waxes, such as paraffin,microcrystalline petroleum, ozocerite, ceresin, and montan; syntheticwaxes, such as low molecular weight polyolefin (e.g., CARBOWAX), andpolyol ether-esters (e.g., sorbitol); Fischer-Tropsch process syntheticwaxes; and mixtures thereof. Water-soluble waxes, such as CARBOWAX andsorbitol, are not contemplated herein if the core is aqueous.

Still other fusible compounds useful herein are fusible natural resins,such as rosin, balsam, shellac, and mixtures thereof.

Various adjunct materials are contemplated for incorporation in fusiblematerials according to the present disclosure. For example,antioxidants, light stabilizers, dyes and lakes, flavors, essentialoils, anti-caking agents, fillers, pH stabilizers, sugars(monosaccharides, disaccharides, trisaccharides, and polysaccharides)and the like can be incorporated in the fusible material in amountswhich do not diminish its utility for the present disclosure.

The core material contemplated herein constitutes from about 0.1% toabout 50%, about 1% to about 35%. or about 5% to about 30% by weight ofthe microcapsules. In some embodiments, the core material contemplatedherein constitutes no more than about 30% by weight of themicrocapsules. In some embodiments, the core material contemplatedherein constitutes about 5% by weight of the microcapsules. The corematerial is contemplated as either a liquid or solid at contemplatedstorage temperatures of the microcapsules.

The cores may include other additives well-known in the pharmaceuticalart, including edible sugars, such as sucrose, glucose, maltose,fructose, lactose, cellobiose, monosaccharides, disaccharides,trisaccharides, polysaccharides, and mixtures thereof; artificialsweeteners, such as aspartame, saccharin, cyclamate salts, and mixturesthereof edible acids, such as acetic acid (vinegar), citric acid,ascorbic acid, tartaric acid, and mixtures thereof; edible starches,such as corn starch; hydrolyzed vegetable protein; water-solublevitamins, such as Vitamin C; water-soluble medicaments; water-solublenutritional materials, such as ferrous sulfate; flavors; salts;monosodium glutamate; antimicrobial agents, such as sorbic acid;antimycotic agents, such as potassium sorbate, sorbic acid, sodiumbenzoate, and benzoic acid; food grade pigments and dyes; and mixturesthereof. Other potentially useful supplemental core materials will beapparent to those of ordinary skill in the art.

Emulsifying agents may be employed to assist in the formation of stableemulsions. Representative emulsifying agents include glycerylmonostearate, polysorbate esters, ethoxylated mono- and diglycerides,and mixtures thereof.

For ease of processing, and particularly to enable the successfulformation of a reasonably stable emulsion, the viscosities of the corematerial and the shell material should be similar at the temperature atwhich the emulsion is formed. In particular, the ratio of the viscosityof the shell to the viscosity of the core, expressed in centipoise orcomparable units, and both measured at the temperature of the emulsion,should be from about 22:1 to about 1:1, desirably from about 8:1 toabout 1:1, and preferably from about 3:1 to about 1:1. A ratio of 1:1would be ideal, but a viscosity ratio within the recited ranges isuseful.

In some embodiments, the microbial cells can be coated freely onto anynumber of compositions or they can be formulated in a liquid or solidcomposition before being coated onto a composition. For example, a solidcomposition comprising the microorganisms can be prepared by mixing asolid carrier with a suspension of the spores until the solid carriersare impregnated with the spore or cell suspension. This mixture can thenbe dried to obtain the desired particles.

In some other embodiments, it is contemplated that the solid or liquidmicrobial compositions of the present disclosure further containfunctional agents e.g., activated carbon, minerals, vitamins, and otheragents capable of improving the quality of the products or a combinationthereof.

Methods of coating and compositions in use of said methods that areknown in the art can be particularly useful when they are modified bythe addition of one of the embodiments of the present disclosure. Suchcoating methods and apparatus for their application are disclosed in,for example: U.S. Pat. Nos. 8,097,245, and 7,998,502; and PCT Pat. App.Publication Nos. WO 2008/076975, WO 2010/138522, WO 2011/094469, WO2010/111347, and WO 2010/111565 each of which is incorporated byreference herein.

In some embodiments, the microbes or microbial consortia of the presentdisclosure exhibit a synergistic effect, on one or more of the traitsdescribed herein, in the presence of one or more of the microbes orconsortia coming into contact with one another. The synergistic effectobtained by the taught methods can be quantified, for example, accordingto Colby's formula (i.e., (E)=X+Y−(X*Y/100)). See Colby, R. S.,“Calculating Synergistic and Antagonistic Responses of HerbicideCombinations,” 1967. Weeds. Vol. 15, pp. 20-22, incorporated herein byreference in its entirety. Thus, “synergistic” is intended to reflect anoutcome/parameter/effect that has been increased by more than anadditive amount.

In some embodiments, the microbes or microbial consortia of the presentdisclosure may be administered via bolus. In one embodiment, a bolus(e.g., capsule containing the composition) is inserted into a bolus gun,and the bolus gun is inserted into the buccal cavity and/or esophagas ofthe animal, followed by the release/injection of the bolus into theanimal's digestive tract. In one embodiment, the bolus gun/applicator isa BOVIKALC bolus gun/applicator. In another embodiment, the bolusgun/applicator is a QUADRICAL gun/applicator.

In some embodiments, the microbes or microbial consortia of the presentdisclosure may be administered via drench. In one embodiment, the drenchis an oral drench. A drench administration comprises utilizing a drenchkit/applicator/syringe that injects/releases a liquid comprising themicrobes or microbial consortia into the buccal cavity and/or esophagasof the animal.

In some embodiments, the microbes or microbial consortia of the presentdisclosure may be administered in a time-released fashion. Thecomposition may be coated in a chemical composition, or may be containedin a mechanical device or capsule that releases the microbes ormicrobial consortia over a period of time instead all at once. In oneembodiment, the microbes or microbial consortia are administered to ananimal in a time-release capsule. In one embodiment, the composition maybe coated in a chemical composition, or may be contained in a mechanicaldevice or capsule that releases the microbes or microbial consortia allat once a period of time hours post ingestion.

In some embodiments, the microbes or microbial consortia areadministered in a time-released fashion between 1 to 5, 1 to 10, 1 to15, 1 to 20, 1 to 24, 1 to 25, 1 to 30, 1 to 35, 1 to 40, 1 to 45, 1 to50, 1 to 55, 1 to 60, 1 to 65, 1 to 70, 1 to 75, 1 to 80, 1 to 85, 1 to90, 1 to 95, or 1 to 100 hours.

Microorganisms

As used herein the term “microorganism” should be taken broadly. Itincludes, but is not limited to, the two prokaryotic domains, Bacteriaand Archaea, as well as eukaryotic fungi, protists, and viruses.

By way of example, the microorganisms may include species of the generaof: Clostridium, Ruminococcus, Roseburia, Hydrogenoanaerobacterium,Saccharofermentans, Papillibacter, Pelotomaculum, Butyricicoccus,Tannerella, Prevotella, Butyricimonas, Piromyces, Pichia, Candida,Vrystaatia, Orpinomyces, Neocallimastix, and Phyllosticta. Themicroorganisms may further include species belonging to the family ofLachnospiraceae, and the order of Saccharomycetales. In someembodiments, the microorganisms may include species of any generadisclosed herein.

In certain embodiments, the microorganism is unculturable. This shouldbe taken to mean that the microorganism is not known to be culturable oris difficult to culture using methods known to one skilled in the art.

In one embodiment, the microbes are obtained from animals (e.g.,mammals, reptiles, birds, and the like), soil (e.g., rhizosphere), air,water (e.g., marine, freshwater, wastewater sludge), sediment, oil,plants (e.g., roots, leaves, stems), agricultural products, and extremeenvironments (e.g., acid mine drainage or hydrothermal systems). In afurther embodiment, microbes obtained from marine or freshwaterenvironments such as an ocean, river, or lake. In a further embodiment,the microbes can be from the surface of the body of water, or any depthof the body of water (e.g., a deep sea sample).

The microorganisms of the disclosure may be isolated in substantiallypure or mixed cultures. They may be concentrated, diluted, or providedin the natural concentrations in which they are found in the sourcematerial. For example, microorganisms from saline sediments may beisolated for use in this disclosure by suspending the sediment in freshwater and allowing the sediment to fall to the bottom. The watercontaining the bulk of the microorganisms may be removed by decantationafter a suitable period of settling and either administered to the GItract of an ungulate, or concentrated by filtering or centrifugation,diluted to an appropriate concentration and administered to the GI tractof an ungulate with the bulk of the salt removed. By way of furtherexample, microorganisms from mineralized or toxic sources may besimilarly treated to recover the microbes for application to theungulate to minimize the potential for damage to the animal.

In another embodiment, the microorganisms are used in a crude form, inwhich they are not isolated from the source material in which theynaturally reside. For example, the microorganisms are provided incombination with the source material in which they reside; for example,fecal matter, cud, or other composition found in the gastrointestinaltract. In this embodiment, the source material may include one or morespecies of microorganisms.

In some embodiments, a mixed population of microorganisms is used in themethods of the disclosure.

In embodiments of the disclosure where the microorganisms are isolatedfrom a source material (for example, the material in which theynaturally reside), any one or a combination of a number of standardtechniques which will be readily known to skilled persons may be used.However, by way of example, these in general employ processes by which asolid or liquid culture of a single microorganism can be obtained in asubstantially pure form, usually by physical separation on the surfaceof a solid microbial growth medium or by volumetric dilutive isolationinto a liquid microbial growth medium. These processes may includeisolation from dry material, liquid suspension, slurries or homogenatesin which the material is spread in a thin layer over an appropriatesolid gel growth medium, or serial dilutions of the material made into asterile medium and inoculated into liquid or solid culture media.

Whilst not essential, in one embodiment, the material containing themicroorganisms may be pre-treated prior to the isolation process inorder to either multiply all microorganisms in the material.Microorganisms can then be isolated from the enriched materials asdisclosed above.

In certain embodiments, as mentioned herein before, the microorganism(s)may be used in crude form and need not be isolated from an animal or amedia. For example, cud, feces, or growth media which includes themicroorganisms identified to be of benefit to increased milk productionin ungulates may be obtained and used as a crude source ofmicroorganisms for the next round of the method or as a crude source ofmicroorganisms at the conclusion of the method. For example, fresh fecescould be obtained and optionally processed.

Microbiome Shift and Abundance of Microbes

In some embodiments, the microbiome of a ruminant, including the rumenmicrobiome, comprises a diverse arrive of microbes with a wide varietyof metabolic capabilities. The microbiome is influenced by a range offactors including diet, variations in animal metabolism, and breed,among others. Most bovine diets are plant-based and rich in complexpolysaccharides that enrich the gastrointestinal microbial community formicrobes capable of breaking down specific polymeric components in thediet. The end products of primary degradation sustains a chain ofmicrobes that ultimately produce a range of organic acids together withhydrogen and carbon dioxide. Because of the complex and interlinkednature of the microbiome, changing the diet and thus substrates forprimary degradation may have a cascading effect on rumen microbialmetabolism, with changes in both the organic acid profiles and themethane levels produced, thus impacting the quality and quantity ofanimal production and or the products produced by the animal. SeeMenezes et al. (2011. FEMS Microbiol. Ecol. 78(2):256-265.)

In some aspects, the present disclosure is drawn to administeringmicrobial compositions described herein to modulate or shift themicrobiome of a ruminant.

In some embodiments, the microbiome is shifted through theadministration of one or more microbes to the gastrointestinal tract. Infurther embodiments, the one or more microbes are those selected fromTable 1 or Table 3. In some embodiments, the microbiome shift ormodulation includes a decrease or loss of specific microbes that werepresent prior to the administration of one or more microbes of thepresent disclosure. In some embodiments, the microbiome shift ormodulation includes an increase in microbes that were present prior tothe administration of one or more microbes of the present disclosure. Insome embodiments, the microbiome shift or modulation includes a gain ofone or more microbes that were not present prior to the administrationof one or more microbes of the present disclosure. In a furtherembodiment, the gain of one or more microbes is a microbe that was notspecifically included in the administered microbial consortium.

In some embodiments, the administration of microbes of the presentdisclosure results in a sustained modulation of the microbiome such thatthe administered microbes are present in the microbiome for a period ofat least 1 to 10, 1 to 9, 1 to 8, 1 to 7, 1 to 6, 1 to 5, 1 to 4, 1 to3, 1 to 2, 2 to 10, 2 to 9, 2 to 8, 2 to 7, 2 to 6, 2 to 5, 2 to 4, 2 to3, 3 to 10, 3 to 9, 3 to 8, 3 to 7, 3 to 6, 3 to 5, 3 to 4, 4 to 10, 4to 9, 4 to 8, 4 to 7, 4 to 6, 4 to 5, 5 to 10, 5 to 9, 5 to 8, 5 to 7, 5to 6, 6 to 10, 6 to 9, 6 to 8, 6 to 7, 7 to 10, 7 to 9, 7 to 8, 8 to 10,8 to 9, 9 to 10, 1, 2, 3, 4, 5, 6, 7, 8, 9, or 10 days.

In some embodiments, the administration of microbes of the presentdisclosure results in a sustained modulation of the microbiome such thatthe administered microbes are present in the microbiome for a period ofat least 1 to 10, 1 to 9, 1 to 8, 1 to 7, 1 to 6, 1 to 5, 1 to 4, 1 to3, 1 to 2, 2 to 10, 2 to 9, 2 to 8, 2 to 7, 2 to 6, 2 to 5, 2 to 4, 2 to3, 3 to 10, 3 to 9, 3 to 8, 3 to 7, 3 to 6, 3 to 5, 3 to 4, 4 to 10, 4to 9, 4 to 8, 4 to 7, 4 to 6, 4 to 5, 5 to 10, 5 to 9, 5 to 8, 5 to 7, 5to 6, 6 to 10, 6 to 9, 6 to 8, 6 to 7, 7 to 10, 7 to 9, 7 to 8, 8 to 10,8 to 9, 9 to 10, 1, 2, 3, 4, 5, 6, 7, 8, 9, or 10 weeks.

In some embodiments, the administration of microbes of the presentdisclosure results in a sustained modulation of the microbiome such thatthe administered microbes are present in the microbiome for a period ofat least 1 to 10, 1 to 9, 1 to 8, 1 to 7, 1 to 6, 1 to 5, 1 to 4, 1 to3, 1 to 2, 2 to 10, 2 to 9, 2 to 8, 2 to 7, 2 to 6, 2 to 5, 2 to 4, 2 to3, 3 to 10, 3 to 9, 3 to 8, 3 to 7, 3 to 6, 3 to 5, 3 to 4, 4 to 10, 4to 9, 4 to 8, 4 to 7, 4 to 6, 4 to 5, 5 to 10, 5 to 9, 5 to 8, 5 to 7, 5to 6, 6 to 10, 6 to 9, 6 to 8, 6 to 7, 7 to 10, 7 to 9, 7 to 8, 8 to 10,8 to 9, 9 to 10, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, or 12 months.

In some embodiments, the presence of the administered microbes aredetected by sampling the gastrointestinal tract and using primers toamplify the 16S or 18S rDNA sequences, or the ITS rDNA sequences of theadministered microbes. In some embodiments, the administered microbesare one or more of those selected from Table 1 or Table 3, and thecorresponding rDNA sequences are those selected from SEQ ID NOs:1-60,SEQ ID NOs:2045-2107 and the SEQ ID NOs identified in Table 3.

In some embodiments, the microbiome of a ruminant is measured byamplifying polynucleotides collected from gastrointestinal samples,wherein the polynucleotides may be 16S or 18S rDNA fragments, or ITSrDNA fragments of microbial rDNA. In one embodiment, the microbiome isfingerprinted by a method of denaturing gradient gel electrophoresis(DGGE) wherein the amplified rDNA fragments are sorted by where theydenature, and form a unique banding pattern in a gel that may be usedfor comparing the microbiome of the same ruminant over time or themicrobiomes of multiple ruminants. In another embodiment, the microbiomeis fingerprinted by a method of terminal restriction fragment lengthpolymorphism (T-RFLP), wherein labelled PCR fragments are digested usinga restriction enzyme and then sorted by size. In a further embodiment,the data collected from the T-RFLP method is evaluated by nonmetricmultidimensional scaling (nMDS) ordination and PERMANOVA statisticsidentify differences in microbiomes, thus allowing for theidentification and measurement of shifts in the microbiome. See alsoShanks et al. (2011. Appl. Environ. Microbiol. 77(9):2992-3001), Petriet al. (2013. PLOS one. 8(12):e83424), and Menezes et al. (2011. FEMSMicrobiol. Ecol. 78(2):256-265.)

In some embodiments, the administration of microbes of the presentdisclosure results in a modulation or shift of the microbiome whichfurther results in a desired phenotype or improved trait.

According to the methods provided herein, a sample is processed todetect the presence of one or more microorganism types in the sample(FIG. 1, 1001; FIG. 2, 2001). The absolute number of one or moremicroorganism organism type in the sample is determined (FIG. 1, 1002;FIG. 2, 2002). The determination of the presence of the one or moreorganism types and the absolute number of at least one organism type canbe conducted in parallel or serially. For example, in the case of asample comprising a microbial community comprising bacteria (i.e., onemicroorganism type) and fungi (i.e., a second microorganism type), theuser in one embodiment detects the presence of one or both of theorganism types in the sample (FIG. 1, 1001; FIG. 2, 2001). The user, ina further embodiment, determines the absolute number of at least oneorganism type in the sample—in the case of this example, the number ofbacteria, fungi or combination thereof, in the sample (FIG. 1, 1002;FIG. 2, 2002).

In one embodiment, the sample, or a portion thereof is subjected to flowcytometry (FC) analysis to detect the presence and/or number of one ormore microorganism types (FIG. 1, 1001, 1002; FIG. 2, 2001, 2002). Inone flow cytometer embodiment, individual microbial cells pass throughan illumination zone, at a rate of at least about 300*s⁻¹, or at leastabout 500*s⁻¹, or at least about 1000*s⁻¹. However, one of ordinaryskill in the art will recognize that this rate can vary depending on thetype of instrument is employed. Detectors which are gated electronicallymeasure the magnitude of a pulse representing the extent of lightscattered. The magnitudes of these pulses are sorted electronically into“bins” or “channels,” permitting the display of histograms of the numberof cells possessing a certain quantitative property (e.g., cell stainingproperty, diameter, cell membrane) versus the channel number. Suchanalysis allows for the determination of the number of cells in each“bin” which in embodiments described herein is an “microorganism type”bin, e.g., a bacteria, fungi, nematode, protozoan, archaea, algae,dinoflagellate, virus, viroid, etc.

In one embodiment, a sample is stained with one or more fluorescent dyeswherein a fluorescent dye is specific to a particular microorganismtype, to enable detection via a flow cytometer or some other detectionand quantification method that harnesses fluorescence, such asfluorescence microscopy. The method can provide quantification of thenumber of cells and/or cell volume of a given organism type in a sample.In a further embodiment, as described herein, flow cytometry isharnessed to determine the presence and quantity of a unique firstmarker and/or unique second marker of the organism type, such as enzymeexpression, cell surface protein expression, etc. Two- or three-variablehistograms or contour plots of, for example, light scattering versusfluorescence from a cell membrane stain (versus fluorescence from aprotein stain or DNA stain) may also be generated, and thus animpression may be gained of the distribution of a variety of propertiesof interest among the cells in the population as a whole. A number ofdisplays of such multiparameter flow cytometric data are in common useand are amenable for use with the methods described herein.

In one embodiment of processing the sample to detect the presence andnumber of one or more microorganism types, a microscopy assay isemployed (FIG. 1, 1001, 1002). In one embodiment, the microscopy isoptical microscopy, where visible light and a system of lenses are usedto magnify images of small samples. Digital images can be captured by acharge-couple device (CCD) camera. Other microscopic techniques include,but are not limited to, scanning electron microscopy and transmissionelectron microscopy. Microorganism types are visualized and quantifiedaccording to the aspects provided herein.

In another embodiment of in order to detect the presence and number ofone or more microorganism types, the sample, or a portion thereof issubjected to fluorescence microscopy. Different fluorescent dyes can beused to directly stain cells in samples and to quantify total cellcounts using an epifluorescence microscope as well as flow cytometry,described above. Useful dyes to quantify microorganisms include but arenot limited to acridine orange (AO), 4,6-di-amino-2 phenylindole (DAPI)and 5-cyano-2,3 Dytolyl Tetrazolium Chloride (CTC). Viable cells can beestimated by a viability staining method such as the LIVE/DEAD®Bacterial Viability Kit (Bac-Light™) which contains two nucleic acidstains: the green-fluorescent SYTO 9™ dye penetrates all membranes andthe red-fluorescent propidium iodide (PI) dye penetrates cells withdamaged membranes. Therefore, cells with compromised membranes willstain red, whereas cells with undamaged membranes will stain green.Fluorescent in situ hybridization (FISH) extends epifluorescencemicroscopy, allowing for the fast detection and enumeration of specificorganisms. FISH uses fluorescent labelled oligonucleotides probes(usually 15-25 basepairs) which bind specifically to organism DNA in thesample, allowing the visualization of the cells using an epifluorescenceor confocal laser scanning microscope (CLSM). Catalyzed reporterdeposition fluorescence in situ hybridization (CARD-FISH) improves uponthe FISH method by using oligonucleotide probes labelled with a horseradish peroxidase (HRP) to amplify the intensity of the signal obtainedfrom the microorganisms being studied. FISH can be combined with othertechniques to characterize microorganism communities. One combinedtechnique is high affinity peptide nucleic acid (PNA)-FISH, where theprobe has an enhanced capability to penetrate through the ExtracellularPolymeric Substance (EPS) matrix. Another example is LIVE/DEAD-FISHwhich combines the cell viability kit with FISH and has been used toassess the efficiency of disinfection in drinking water distributionsystems.

In another embodiment, the sample, or a portion thereof is subjected toRaman micro-spectroscopy in order to determine the presence of amicroorganism type and the absolute number of at least one microorganismtype (FIG. 1, 1001-1002; FIG. 2, 2001-2002). Raman micro-spectroscopy isa non-destructive and label-free technology capable of detecting andmeasuring a single cell Raman spectrum (SCRS). A typical SCRS providesan intrinsic biochemical “fingerprint” of a single cell. A SCRS containsrich information of the biomolecules within it, including nucleic acids,proteins, carbohydrates and lipids, which enables characterization ofdifferent cell species, physiological changes and cell phenotypes. Ramanmicroscopy examines the scattering of laser light by the chemical bondsof different cell biomarkers. A SCRS is a sum of the spectra of all thebiomolecules in one single cell, indicating a cell's phenotypic profile.Cellular phenotypes, as a consequence of gene expression, usuallyreflect genotypes. Thus, under identical growth conditions, differentmicroorganism types give distinct SCRS corresponding to differences intheir genotypes and can thus be identified by their Raman spectra.

In yet another embodiment, the sample, or a portion thereof is subjectedto centrifugation in order to determine the presence of a microorganismtype and the number of at least one microorganism type (FIG. 1,1001-1002; FIG. 2, 2001-2002). This process sediments a heterogeneousmixture by using the centrifugal force created by a centrifuge. Moredense components of the mixture migrate away from the axis of thecentrifuge, while less dense components of the mixture migrate towardsthe axis. Centrifugation can allow fractionation of samples intocytoplasmic, membrane and extracellular portions. It can also be used todetermine localization information for biological molecules of interest.Additionally, centrifugation can be used to fractionate total microbialcommunity DNA. Different prokaryotic groups differ in theirguanine-plus-cytosine (G+C) content of DNA, so density-gradientcentrifugation based on G+C content is a method to differentiateorganism types and the number of cells associated with each type. Thetechnique generates a fractionated profile of the entire community DNAand indicates abundance of DNA as a function of G+C content. The totalcommunity DNA is physically separated into highly purified fractions,each representing a different G+C content that can be analyzed byadditional molecular techniques such as denaturing gradient gelelectrophoresis (DGGE)/amplified ribosomal DNA restriction analysis(ARDRA) (see discussion herein) to assess total microbial communitydiversity and the presence/quantity of one or more microorganism types.

In another embodiment, the sample, or a portion thereof is subjected tostaining in order to determine the presence of a microorganism type andthe number of at least one microorganism type (FIG. 1, 1001-1002; FIG.2, 2001-2002). Stains and dyes can be used to visualize biologicaltissues, cells or organelles within cells. Staining can be used inconjunction with microscopy, flow cytometry or gel electrophoresis tovisualize or mark cells or biological molecules that are unique todifferent microorganism types. In vivo staining is the process of dyeingliving tissues, whereas in vitro staining involves dyeing cells orstructures that have been removed from their biological context.Examples of specific staining techniques for use with the methodsdescribed herein include, but are not limited to: gram staining todetermine gram status of bacteria, endospore staining to identify thepresence of endospores, Ziehl-Neelsen staining, haematoxylin and eosinstaining to examine thin sections of tissue, papanicolaou staining toexamine cell samples from various bodily secretions, periodicacid-Schiff staining of carbohydrates, Masson's trichome employing athree-color staining protocol to distinguish cells from the surroundingconnective tissue, Romanowsky stains (or common variants that includeWright's stain, Jenner's stain, May-Grunwald stain, Leishman stain andGiemsa stain) to examine blood or bone marrow samples, silver stainingto reveal proteins and DNA, Sudan staining for lipids and Conklin'sstaining to detect true endospores. Common biological stains includeacridine orange for cell cycle determination; bismarck brown for acidmucins; carmine for glycogen; carmine alum for nuclei; Coomassie bluefor proteins; Cresyl violet for the acidic components of the neuronalcytoplasm; Crystal violet for cell walls; DAPI for nuclei; eosin forcytoplasmic material, cell membranes, some extracellular structures andred blood cells; ethidium bromide for DNA; acid fuchsine for collagen,smooth muscle or mitochondria; haematoxylin for nuclei; Hoechst stainsfor DNA; iodine for starch; malachite green for bacteria in the Gimenezstaining technique and for spores; methyl green for chromatin; methyleneblue for animal cells; neutral red for Nissl substance; Nile blue fornuclei; Nile red for lipohilic entities; osmium tetroxide for lipids;rhodamine is used in fluorescence microscopy; safranin for nuclei.Stains are also used in transmission electron microscopy to enhancecontrast and include phosphotungstic acid, osmium tetroxide, rutheniumtetroxide, ammonium molybdate, cadmium iodide, carbohydrazide, ferricchloride, hexamine, indium trichloride, lanthanum nitrate, lead acetate,lead citrate, lead(II) nitrate, periodic acid, phosphomolybdic acid,potassium ferricyanide, potassium ferrocyanide, ruthenium red, silvernitrate, silver proteinate, sodium chloroaurate, thallium nitrate,thiosemicarbazide, uranyl acetate, uranyl nitrate, and vanadyl sulfate.

In another embodiment, the sample, or a portion thereof is subjected tomass spectrometry (MS) in order to determine the presence of amicroorganism type and the number of at least one microorganism type(FIG. 1, 1001-1002; FIG. 2, 2001-2002). MS, as discussed below, can alsobe used to detect the presence and expression of one or more uniquemarkers in a sample (FIG. 1, 1003-1004; FIG. 2, 2003-2004). MS is usedfor example, to detect the presence and quantity of protein and/orpeptide markers unique to microorganism types and therefore to providean assessment of the number of the respective microorganism type in thesample. Quantification can be either with stable isotope labelling orlabel-free. De novo sequencing of peptides can also occur directly fromMS/MS spectra or sequence tagging (produce a short tag that can bematched against a database). MS can also reveal post-translationalmodifications of proteins and identify metabolites. MS can be used inconjunction with chromatographic and other separation techniques (suchas gas chromatography, liquid chromatography, capillary electrophoresis,ion mobility) to enhance mass resolution and determination.

In another embodiment, the sample, or a portion thereof is subjected tolipid analysis in order to determine the presence of a microorganismtype and the number of at least one microorganism type (FIG. 1,1001-1002; FIG. 2, 2001-2002). Fatty acids are present in a relativelyconstant proportion of the cell biomass, and signature fatty acids existin microbial cells that can differentiate microorganism types within acommunity. In one embodiment, fatty acids are extracted bysaponification followed by derivatization to give the respective fattyacid methyl esters (FAMEs), which are then analyzed by gaschromatography. The FAME profile in one embodiment is then compared to areference FAME database to identify the fatty acids and theircorresponding microbial signatures by multivariate statistical analyses.

In the aspects of the methods provided herein, the number of uniquefirst makers in the sample, or portion thereof (e.g., sample aliquot) ismeasured, as well as the abundance of each of the unique first markers(FIG. 1, 1003; FIG. 2, 2003). A unique marker is a marker of amicroorganism strain. It should be understood by one of ordinary skillin the art that depending on the unique marker being probed for andmeasured, the entire sample need not be analyzed. For example, if theunique marker is unique to bacterial strains, then the fungal portion ofthe sample need not be analyzed. As described above, in someembodiments, measuring the absolute abundance of one or more organismtypes in a sample comprises separating the sample by organism type,e.g., via flow cytometry.

Any marker that is unique to an organism strain can be employed herein.For example, markers can include, but are not limited to, small subunitribosomal RNA genes (16S/18S rDNA), large subunit ribosomal RNA genes(23S/25S/28S rDNA), intercalary 5.8S gene, cytochrome c oxidase,beta-tubulin, elongation factor, RNA polymerase and internal transcribedspacer (ITS).

Ribosomal RNA genes (rDNA), especially the small subunit ribosomal RNAgenes, i.e., 18S rRNA genes (18S rDNA) in the case of eukaryotes and 16SrRNA (16S rDNA) in the case of prokaryotes, have been the predominanttarget for the assessment of organism types and strains in a microbialcommunity. However, the large subunit ribosomal RNA genes, 28S rDNAs,have been also targeted. rDNAs are suitable for taxonomic identificationbecause: (i) they are ubiquitous in all known organisms; (ii) theypossess both conserved and variable regions; (iii) there is anexponentially expanding database of their sequences available forcomparison. In community analysis of samples, the conserved regionsserve as annealing sites for the corresponding universal PCR and/orsequencing primers, whereas the variable regions can be used forphylogenetic differentiation. In addition, the high copy number of rDNAin the cells facilitates detection from environmental samples.

The internal transcribed spacer (ITS), located between the 18S rDNA and28S rDNA, has also been targeted. The ITS is transcribed but splicedaway before assembly of the ribosomes The ITS region is composed of twohighly variable spacers, ITS1 and ITS2, and the intercalary 5.8S gene.This rDNA operon occurs in multiple copies in genomes. Because the ITSregion does not code for ribosome components, it is highly variable.

In one embodiment, the unique RNA marker can be an mRNA marker, an siRNAmarker or a ribosomal RNA marker.

Protein-coding functional genes can also be used herein as a uniquefirst marker. Such markers include but are not limited to: therecombinase A gene family (bacterial RecA, archaea RadA and RadB,eukaryotic Rad51 and Rad57, phage UvsX); RNA polymerase β subunit (RpoB)gene, which is responsible for transcription initiation and elongation;chaperonins. Candidate marker genes have also been identified forbacteria plus archaea: ribosomal protein S2 (rpsB), ribosomal proteinS10 (rpsJ), ribosomal protein L1 rplA), translation elongation factorEF-2, translation initiation factor IF-2, metalloendopeptidase,ribosomal protein L22, ffh signal recognition particle protein,ribosomal protein L4/L1e (rplD), ribosomal protein L2 (rplB), ribosomalprotein S9 (rpsl), ribosomal protein L3 (rplC), phenylalanyl-tRNAsynthetase beta subunit, ribosomal protein L14b/L23e (rplN), ribosomalprotein S5, ribosomal protein S19 (rpsS), ribosomal protein S7,ribosomal protein L16/L10E (rplP), ribosomal protein S13 (rpsM),phenylalanyl-tRNA synthetase α subunit, ribosomal protein L15, ribosomalprotein L25/L23, ribosomal protein L6 (rplF), ribosomal protein L11(rplK), ribosomal protein L5 (rplE), ribosomal protein S12/S23,ribosomal protein L29, ribosomal protein S3 (rpsC), ribosomal proteinS11 (rpsK), ribosomal protein L10, ribosomal protein S8, tRNApseudouridine synthase B, ribosomal protein L18P/L5E, ribosomal proteinS15P/S13e, Porphobilinogen deaminase, ribosomal protein S17, ribosomalprotein L13 (rplM), phosphoribosylformylglycinamidine cyclo-ligase(rpsE), ribonuclease HII and ribosomal protein L24. Other candidatemarker genes for bacteria include: transcription elongation protein NusA(nusA), rpoB DNA-directed RNA polymerase subunit beta (rpoB),GTP-binding protein EngA, rpoC DNA-directed RNA polymerase subunitbeta′, priA primosome assembly protein, transcription-repair couplingfactor, CTP synthase (pyrG), secY preprotein translocase subunit SecY,GTP-binding protein Obg/CgtA, DNA polymerase I, rpsF 30S ribosomalprotein S6, poA DNA-directed RNA polymerase subunit alpha, peptide chainrelease factor 1, rplI 50S ribosomal protein L9, polyribonucleotidenucleotidyltransferase, tsf elongation factor Ts (tsf), rplQ 50Sribosomal protein L17, tRNA (guanine-N(1)-)-methyltransferase (rplS),rplY probable 50S ribosomal protein L25, DNA repair protein RadA,glucose-inhibited division protein A, ribosome-binding factor A, DNAmismatch repair protein MutL, smpB SsrA-binding protein (smpB),N-acetylglucosaminyl transferase, S-adenosyl-methyltransferase MraW,UDP-N-acetylmuramoylalanine-D-glutamate ligase, rplS 50S ribosomalprotein L19, rplT 50S ribosomal protein L20 (rplT), ruvA Hollidayjunction DNA helicase, ruvB Holliday junction DNA helicase B, serSseryl-tRNA synthetase, rplU 50S ribosomal protein L21, rpsR 30Sribosomal protein S18, DNA mismatch repair protein MutS, rpsT 30Sribosomal protein S20, DNA repair protein RecN, frr ribosome recyclingfactor (frr), recombination protein RecR, protein of unknown functionUPF0054, miaA tRNA isopentenyltransferase, GTP-binding protein YchF,chromosomal replication initiator protein DnaA, dephospho-CoA kinase,16S rRNA processing protein RimM, ATP-cone domain protein,1-deoxy-D-xylulose 5-phosphate reductoisomerase, 2C-methyl-D-erythritol2,4-cyclodiphosphate synthase, fatty acid/phospholipid synthesis proteinPlsX, tRNA(Ile)-lysidine synthetase, dnaG DNA primase (dnaG), ruvCHolliday junction resolvase, rpsP 30S ribosomal protein S16, RecombinaseA recA, riboflavin biosynthesis protein RibF, glycyl-tRNA synthetasebeta subunit, trmU tRNA(5-methylaminomethyl-2-thiouridylate)-methyltransferase, rpmI 50Sribosomal protein L35, hemE uroporphyrinogen decarboxylase, Rodshape-determining protein, rpmA 50S ribosomal protein L27 (rpmA),peptidyl-tRNA hydrolase, translation initiation factor IF-3 (infC),UDP-N-acetylmuramyl-tripeptide synthetase, rpmF 50S ribosomal proteinL32, rpIL 50S ribosomal protein L7/L12 (rpIL), leuS leucyl-tRNAsynthetase, ligA NAD-dependent DNA ligase, cell division protein FtsA,GTP-binding protein TypA, ATP-dependent Clp protease, ATP-bindingsubunit ClpX, DNA replication and repair protein RecF andUDP-N-acetylenolpyruvoylglucosamine reductase.

Phospholipid fatty acids (PLFAs) may also be used as unique firstmarkers according to the methods described herein. Because PLFAs arerapidly synthesized during microbial growth, are not found in storagemolecules and degrade rapidly during cell death, it provides an accuratecensus of the current living community. All cells contain fatty acids(FAs) that can be extracted and esterified to form fatty acid methylesters (FAMEs). When the FAMEs are analyzed using gaschromatography-mass spectrometry, the resulting profile constitutes a‘fingerprint’ of the microorganisms in the sample. The chemicalcompositions of membranes for organisms in the domains Bacteria andEukarya are comprised of fatty acids linked to the glycerol by anester-type bond (phospholipid fatty acids (PLFAs)). In contrast, themembrane lipids of Archaea are composed of long and branchedhydrocarbons that are joined to glycerol by an ether-type bond(phospholipid ether lipids (PLELs)). This is one of the most widely usednon-genetic criteria to distinguish the three domains. In this context,the phospholipids derived from microbial cell membranes, characterizedby different acyl chains, are excellent signature molecules, becausesuch lipid structural diversity can be linked to specific microbialtaxa.

As provided herein, in order to determine whether an organism strain isactive, the level of expression of one or more unique second markers,which can be the same or different as the first marker, is measured(FIG. 1, 1004; FIG. 2, 2004). Unique first unique markers are describedabove. The unique second marker is a marker of microorganism activity.For example, in one embodiment, the mRNA or protein expression of any ofthe first markers described above is considered a unique second markerfor the purposes of this invention.

In one embodiment, if the level of expression of the second marker isabove a threshold level (e.g., a control level) or at a threshold level,the microorganism is considered to be active (FIG. 1, 1005; FIG. 2,2005). Activity is determined in one embodiment, if the level ofexpression of the second marker is altered by at least about 5%, atleast about 10%, at least about 15%, at least about 20%, at least about25%, or at least about 30%, as compared to a threshold level, which insome embodiments, is a control level.

Second unique markers are measured, in one embodiment, at the protein,RNA or metabolite level. A unique second marker is the same or differentas the first unique marker.

As provided above, a number of unique first markers and unique secondmarkers can be detected according to the methods described herein.Moreover, the detection and quantification of a unique first marker iscarried out according to methods known to those of ordinary skill in theart (FIG. 1, 1003-1004, FIG. 2, 2003-2004).

Nucleic acid sequencing (e.g., gDNA, cDNA, rRNA, mRNA) in one embodimentis used to determine absolute abundance of a unique first marker and/orunique second marker. Sequencing platforms include, but are not limitedto, Sanger sequencing and high-throughput sequencing methods availablefrom Roche/454 Life Sciences, Illumina/Solexa, Pacific Biosciences, IonTorrent and Nanopore. The sequencing can be amplicon sequencing ofparticular DNA or RNA sequences or whole metagenome/transcriptomeshotgun sequencing.

Traditional Sanger sequencing (Sanger et al. (1977) DNA sequencing withchain-terminating inhibitors. Proc Natl. Acad. Sci. USA, 74, pp.5463-5467, incorporated by reference herein in its entirety) relies onthe selective incorporation of chain-terminating dideoxynucleotides byDNA polymerase during in vitro DNA replication and is amenable for usewith the methods described herein.

In another embodiment, the sample, or a portion thereof is subjected toextraction of nucleic acids, amplification of DNA of interest (such asthe rRNA gene) with suitable primers and the construction of clonelibraries using sequencing vectors. Selected clones are then sequencedby Sanger sequencing and the nucleotide sequence of the DNA of interestis retrieved, allowing calculation of the number of unique microorganismstrains in a sample.

454 pyrosequencing from Roche/454 Life Sciences yields long reads andcan be harnessed in the methods described herein (Margulies et al.(2005) Nature, 437, pp. 376-380; U.S. Pat. Nos. 6,274,320; 6,258,568;6,210,891, each of which is herein incorporated in its entirety for allpurposes). Nucleic acid to be sequenced (e.g., amplicons or nebulizedgenomic/metagenomic DNA) have specific adapters affixed on either end byPCR or by ligation. The DNA with adapters is fixed to tiny beads(ideally, one bead will have one DNA fragment) that are suspended in awater-in-oil emulsion. An emulsion PCR step is then performed to makemultiple copies of each DNA fragment, resulting in a set of beads inwhich each bead contains many cloned copies of the same DNA fragment.Each bead is then placed into a well of a fiber-optic chip that alsocontains enzymes necessary for the sequencing-by-synthesis reactions.The addition of bases (such as A, C, G, or T) trigger pyrophosphaterelease, which produces flashes of light that are recorded to infer thesequence of the DNA fragments in each well. About 1 million reads perrun with reads up to 1,000 bases in length can be achieved. Paired-endsequencing can be done, which produces pairs of reads, each of whichbegins at one end of a given DNA fragment. A molecular barcode can becreated and placed between the adapter sequence and the sequence ofinterest in multiplex reactions, allowing each sequence to be assignedto a sample bioinformatically.

Illumina/Solexa sequencing produces average read lengths of about 25basepairs (bp) to about 300 bp (Bennett et al. (2005) Pharmacogenomics,6:373-382; Lange et al. (2014). BMC Genomics 15, p. 63; Fadrosh et al.(2014) Microbiome 2, p. 6; Caporaso et al. (2012) ISME J, 6, p.1621-1624; Bentley et al. (2008) Accurate whole human genome sequencingusing reversible terminator chemistry. Nature, 456:53-59). Thissequencing technology is also sequencing-by-synthesis but employsreversible dye terminators and a flow cell with a field of oligosattached. DNA fragments to be sequenced have specific adapters on eitherend and are washed over a flow cell filled with specificoligonucleotides that hybridize to the ends of the fragments. Eachfragment is then replicated to make a cluster of identical fragments.Reversible dye-terminator nucleotides are then washed over the flow celland given time to attach. The excess nucleotides are washed away, theflow cell is imaged, and the reversible terminators can be removed sothat the process can repeat and nucleotides can continue to be added insubsequent cycles. Paired-end reads that are 300 bases in length eachcan be achieved. An Illumina platform can produce 4 billion fragments ina paired-end fashion with 125 bases for each read in a single run.Barcodes can also be used for sample multiplexing, but indexing primersare used.

The SOLiD (Sequencing by Oligonucleotide Ligation and Detection, LifeTechnologies) process is a “sequencing-by-ligation” approach, and can beused with the methods described herein for detecting the presence andabundance of a first marker and/or a second marker (FIG. 1, 1003-1004;FIG. 2, 2003-2004) (Peckham et al. SOLiD™ Sequencing and 2-BaseEncoding. San Diego, Calif.: American Society of Human Genetics, 2007;Mitra et al. (2013) Analysis of the intestinal microbiota using SOLiD16S rRNA gene sequencing and SOLiD shotgun sequencing. BMC Genomics,14(Suppl 5): S16; Mardis (2008) Next-generation DNA sequencing methods.Annu Rev Genomics Hum Genet, 9:387-402; each incorporated by referenceherein in its entirety). A library of DNA fragments is prepared from thesample to be sequenced, and are used to prepare clonal bead populations,where only one species of fragment will be present on the surface ofeach magnetic bead. The fragments attached to the magnetic beads willhave a universal P1 adapter sequence so that the starting sequence ofevery fragment is both known and identical. Primers hybridize to the P1adapter sequence within the library template. A set of fourfluorescently labelled di-base probes compete for ligation to thesequencing primer. Specificity of the di-base probe is achieved byinterrogating every 1st and 2nd base in each ligation reaction. Multiplecycles of ligation, detection and cleavage are performed with the numberof cycles determining the eventual read length. The SOLiD platform canproduce up to 3 billion reads per run with reads that are 75 bases long.Paired-end sequencing is available and can be used herein, but with thesecond read in the pair being only 35 bases long. Multiplexing ofsamples is possible through a system akin to the one used by Illumina,with a separate indexing run.

The Ion Torrent system, like 454 sequencing, is amenable for use withthe methods described herein for detecting the presence and abundance ofa first marker and/or a second marker (FIG. 1, 1003-1004; FIG. 2,2003-2004). It uses a plate of microwells containing beads to which DNAfragments are attached. It differs from all of the other systems,however, in the manner in which base incorporation is detected. When abase is added to a growing DNA strand, a proton is released, whichslightly alters the surrounding pH. Microdetectors sensitive to pH areassociated with the wells on the plate, and they record when thesechanges occur. The different bases (A, C, G, T) are washed sequentiallythrough the wells, allowing the sequence from each well to be inferred.The Ion Proton platform can produce up to 50 million reads per run thathave read lengths of 200 bases. The Personal Genome Machine platform haslonger reads at 400 bases. Bidirectional sequencing is available.Multiplexing is possible through the standard in-line molecular barcodesequencing.

Pacific Biosciences (PacBio) SMRT sequencing uses a single-molecule,real-time sequencing approach and in one embodiment, is used with themethods described herein for detecting the presence and abundance of afirst marker and/or a second marker (FIG. 1, 1003-1004; FIG. 2,2003-2004). The PacBio sequencing system involves no amplification step,setting it apart from the other major next-generation sequencingsystems. In one embodiment, the sequencing is performed on a chipcontaining many zero-mode waveguide (ZMW) detectors. DNA polymerases areattached to the ZMW detectors and phospholinked dye-labeled nucleotideincorporation is imaged in real time as DNA strands are synthesized. ThePacBio system yields very long read lengths (averaging around 4,600bases) and a very high number of reads per run (about 47,000). Thetypical “paired-end” approach is not used with PacBio, since reads aretypically long enough that fragments, through CCS, can be coveredmultiple times without having to sequence from each end independently.Multiplexing with PacBio does not involve an independent read, butrather follows the standard “in-line” barcoding model.

In one embodiment, where the first unique marker is the ITS genomicregion, automated ribosomal intergenic spacer analysis (ARISA) is usedin one embodiment to determine the number and identity of microorganismstrains in a sample (FIG. 1, 1003, FIG. 2, 2003) (Ranjard et al. (2003).Environmental Microbiology 5, pp. 1111-1120, incorporated by referencein its entirety for all purposes). The ITS region has significantheterogeneity in both length and nucleotide sequence. The use of afluorescence-labeled forward primer and an automatic DNA sequencerpermits high resolution of separation and high throughput. The inclusionof an internal standard in each sample provides accuracy in sizinggeneral fragments.

In another embodiment, fragment length polymorphism (RFLP) ofPCR-amplified rDNA fragments, otherwise known as amplified ribosomal DNArestriction analysis (ARDRA), is used to characterize unique firstmarkers and the abundance of the same in samples (FIG. 1, 1003, FIG. 2,2003) (Massol-Deya et al. (1995). Mol. Microb. Ecol. Manual. 3.3.2, pp.1-18, incorporated by reference in its entirety for all purposes). rDNAfragments are generated by PCR using general primers, digested withrestriction enzymes, electrophoresed in agarose or acrylamide gels, andstained with ethidium bromide or silver nitrate.

One fingerprinting technique used in detecting the presence andabundance of a unique first marker is single-stranded-conformationpolymorphism (SSCP) (Lee et al. (1996). Appl Environ Microbiol 62, pp.3112-3120; Scheinert et al. (1996). J. Microbiol. Methods 26, pp.103-117; Schwieger and Tebbe (1998). Appl. Environ. Microbiol. 64, pp.4870-4876, each of which is incorporated by reference herein in itsentirety). In this technique, DNA fragments such as PCR productsobtained with primers specific for the 16S rRNA gene, are denatured anddirectly electrophoresed on a non-denaturing gel. Separation is based ondifferences in size and in the folded conformation of single-strandedDNA, which influences the electrophoretic mobility. Reannealing of DNAstrands during electrophoresis can be prevented by a number ofstrategies, including the use of one phosphorylated primer in the PCRfollowed by specific digestion of the phosphorylated strands with lambdaexonuclease and the use of one biotinylated primer to perform magneticseparation of one single strand after denaturation. To assess theidentity of the predominant populations in a given consortium, in oneembodiment, bands are excised and sequenced, or SSCP-patterns can behybridized with specific probes. Electrophoretic conditions, such as gelmatrix, temperature, and addition of glycerol to the gel, can influencethe separation.

In addition to sequencing based methods, other methods for quantifyingexpression (e.g., gene, protein expression) of a second marker areamenable for use with the methods provided herein for determining thelevel of expression of one or more second markers (FIG. 1, 1004; FIG. 2,2004). For example, quantitative RT-PCR, microarray analysis, linearamplification techniques such as nucleic acid sequence basedamplification (NASBA) are all amenable for use with the methodsdescribed herein, and can be carried out according to methods known tothose of ordinary skill in the art.

In another embodiment, the sample, or a portion thereof is subjected toa quantitative polymerase chain reaction (PCR) for detecting thepresence and abundance of a first marker and/or a second marker (FIG. 1,1003-1004; FIG. 2, 2003-2004). Specific microorganism strains activityis measured by reverse transcription of transcribed ribosomal and/ormessenger RNA (rRNA and mRNA) into complementary DNA (cDNA), followed byPCR (RT-PCR).

In another embodiment, the sample, or a portion thereof is subjected toPCR-based fingerprinting techniques to detect the presence and abundanceof a first marker and/or a second marker (FIG. 1, 1003-1004; FIG. 2,2003-2004). PCR products can be separated by electrophoresis based onthe nucleotide composition. Sequence variation among the different DNAmolecules influences the melting behaviour, and therefore molecules withdifferent sequences will stop migrating at different positions in thegel. Thus electrophoretic profiles can be defined by the position andthe relative intensity of different bands or peaks and can be translatedto numerical data for calculation of diversity indices. Bands can alsobe excised from the gel and subsequently sequenced to reveal thephylogenetic affiliation of the community members. Electrophoresismethods include, but are not limited to: denaturing gradient gelelectrophoresis (DGGE), temperature gradient gel electrophoresis (TGGE),single-stranded-conformation polymorphism (SSCP), restriction fragmentlength polymorphism analysis (RFLP) or amplified ribosomal DNArestriction analysis (ARDRA), terminal restriction fragment lengthpolymorphism analysis (T-RFLP), automated ribosomal intergenic spaceranalysis (ARISA), randomly amplified polymorphic DNA (RAPD), DNAamplification fingerprinting (DAF) and Bb-PEG electrophoresis.

In another embodiment, the sample, or a portion thereof is subjected toa chip-based platform such as microarray or microfluidics to determinethe abundance of a unique first marker and/or presence/abundance of aunique second marker (FIG. 1, 1003-1004, FIG. 2, 2003-2004). The PCRproducts are amplified from total DNA in the sample and directlyhybridized to known molecular probes affixed to microarrays. After thefluorescently labeled PCR amplicons are hybridized to the probes,positive signals are scored by the use of confocal laser scanningmicroscopy. The microarray technique allows samples to be rapidlyevaluated with replication, which is a significant advantage inmicrobial community analyses. In general, the hybridization signalintensity on microarrays is directly proportional to the abundance ofthe target organism. The universal high-density 16S microarray(PhyloChip) contains about 30,000 probes of 16SrRNA gene targeted toseveral cultured microbial species and “candidate divisions”. Theseprobes target all 121 demarcated prokaryotic orders and allowsimultaneous detection of 8,741 bacterial and archaeal taxa. Anothermicroarray in use for profiling microbial communities is the FunctionalGene Array (FGA). Unlike PhyloChips, FGAs are designed primarily todetect specific metabolic groups of bacteria. Thus, FGA not only revealthe community structure, but they also shed light on the in situcommunity metabolic potential. FGA contain probes from genes with knownbiological functions, so they are useful in linking microbial communitycomposition to ecosystem functions. An FGA termed GeoChipcontains >24,000 probes from all known metabolic genes involved invarious biogeochemical, ecological, and environmental processes such asammonia oxidation, methane oxidation, and nitrogen fixation.

A protein expression assay, in one embodiment, is used with the methodsdescribed herein for determining the level of expression of one or moresecond markers (FIG. 1, 1004; FIG. 2, 2004). For example, in oneembodiment, mass spectrometry or an immunoassay such as an enzyme-linkedimmunosorbant assay (ELISA) is utilized to quantify the level ofexpression of one or more unique second markers, wherein the one or moreunique second markers is a protein.

In one embodiment, the sample, or a portion thereof is subjected toBromodeoxyuridine (BrdU) incorporation to determine the level of asecond unique marker (FIG. 1, 1004; FIG. 2, 2004). BrdU, a syntheticnucleoside analog of thymidine, can be incorporated into newlysynthesized DNA of replicating cells. Antibodies specific for BRdU canthen be used for detection of the base analog. Thus BrdU incorporationidentifies cells that are actively replicating their DNA, a measure ofactivity of a microorganism according to one embodiment of the methodsdescribed herein. BrdU incorporation can be used in combination withFISH to provide the identity and activity of targeted cells.

In one embodiment, the sample, or a portion thereof is subjected tomicroautoradiography (MAR) combined with FISH to determine the level ofa second unique marker (FIG. 1, 1004; FIG. 2, 2004). MAR-FISH is basedon the incorporation of radioactive substrate into cells, detection ofthe active cells using autoradiography and identification of the cellsusing FISH. The detection and identification of active cells atsingle-cell resolution is performed with a microscope. MAR-FISH providesinformation on total cells, probe targeted cells and the percentage ofcells that incorporate a given radiolabelled substance. The methodprovides an assessment of the in situ function of targetedmicroorganisms and is an effective approach to study the in vivophysiology of microorganisms. A technique developed for quantificationof cell-specific substrate uptake in combination with MAR-FISH is knownas quantitative MAR (QMAR).

In one embodiment, the sample, or a portion thereof is subjected tostable isotope Raman spectroscopy combined with FISH (Raman-FISH) todetermine the level of a second unique marker (FIG. 1, 1004; FIG. 2,2004). This technique combines stable isotope probing, Ramanspectroscopy and FISH to link metabolic processes with particularorganisms. The proportion of stable isotope incorporation by cellsaffects the light scatter, resulting in measurable peak shifts forlabelled cellular components, including protein and mRNA components.Raman spectroscopy can be used to identify whether a cell synthesizescompounds including, but not limited to: oil (such as alkanes), lipids(such as triacylglycerols (TAG)), specific proteins (such as hemeproteins, metalloproteins), cytochrome (such as P450, cytochrome c),chlorophyll, chromophores (such as pigments for light harvestingcarotenoids and rhodopsins), organic polymers (such aspolyhydroxyalkanoates (PHA), polyhydroxybutyrate (PHB)), hopanoids,steroids, starch, sulfide, sulfate and secondary metabolites (such asvitamin B12).

In one embodiment, the sample, or a portion thereof is subjected toDNA/RNA stable isotope probing (SIP) to determine the level of a secondunique marker (FIG. 1, 1004; FIG. 2, 2004). SIP enables determination ofthe microbial diversity associated with specific metabolic pathways andhas been generally applied to study microorganisms involved in theutilization of carbon and nitrogen compounds. The substrate of interestis labelled with stable isotopes (such as ¹³C or ¹⁵N) and added to thesample. Only microorganisms able to metabolize the substrate willincorporate it into their cells. Subsequently, ¹³C-DNA and ¹⁵N-DNA canbe isolated by density gradient centrifugation and used for metagenomicanalysis. RNA-based SIP can be a responsive biomarker for use in SIPstudies, since RNA itself is a reflection of cellular activity.

In one embodiment, the sample, or a portion thereof is subjected toisotope array to determine the level of a second unique marker (FIG. 1,1004; FIG. 2, 2004). Isotope arrays allow for functional andphylogenetic screening of active microbial communities in ahigh-throughput fashion. The technique uses a combination of SIP formonitoring the substrate uptake profiles and microarray technology fordetermining the taxonomic identities of active microbial communities.Samples are incubated with a ¹⁴C-labeled substrate, which during thecourse of growth becomes incorporated into microbial biomass. The¹⁴C-labeled rRNA is separated from unlabeled rRNA and then labeled withfluorochromes. Fluorescent labeled rRNA is hybridized to a phylogeneticmicroarray followed by scanning for radioactive and fluorescent signals.The technique thus allows simultaneous study of microbial communitycomposition and specific substrate consumption by metabolically activemicroorganisms of complex microbial communities.

In one embodiment, the sample, or a portion thereof is subjected to ametabolomics assay to determine the level of a second unique marker(FIG. 1, 1004; FIG. 2, 2004). Metabolomics studies the metabolome whichrepresents the collection of all metabolites, the end products ofcellular processes, in a biological cell, tissue, organ or organism.This methodology can be used to monitor the presence of microorganismsand/or microbial mediated processes since it allows associating specificmetabolite profiles with different microorganisms. Profiles ofintracellular and extracellular metabolites associated with microbialactivity can be obtained using techniques such as gaschromatography-mass spectrometry (GC-MS). The complex mixture of ametabolomic sample can be separated by such techniques as gaschromatography, high performance liquid chromatography and capillaryelectrophoresis. Detection of metabolites can be by mass spectrometry,nuclear magnetic resonance (NMR) spectroscopy, ion-mobilityspectrometry, electrochemical detection (coupled to HPLC) and radiolabel(when combined with thin-layer chromatography).

According to the embodiments described herein, the presence andrespective number of one or more active microorganism strains in asample are determined (FIG. 1, 1006; FIG. 2, 2006). For example, strainidentity information obtained from assaying the number and presence offirst markers is analyzed to determine how many occurrences of a uniquefirst marker are present, thereby representing a unique microorganismstrain (e.g., by counting the number of sequence reads in a sequencingassay). This value can be represented in one embodiment as a percentageof total sequence reads of the first maker to give a percentage ofunique microorganism strains of a particular microorganism type. In afurther embodiment, this percentage is multiplied by the number ofmicroorganism types (obtained at step 1002 or 2002, see FIG. 1 and FIG.2) to give the absolute abundance of the one or more microorganismstrains in a sample and a given volume.

The one or more microorganism strains are considered active, asdescribed above, if the level of second unique marker expression at athreshold level, higher than a threshold value, e.g., higher than atleast about 5%, at least about 10%, at least about 20% or at least about30% over a control level.

In another aspect of the invention, a method for determining theabsolute abundance of one or more microorganism strains is determined ina plurality of samples (FIG. 2, see in particular, 2007). For amicroorganism strain to be classified as active, it need only be activein one of the samples. The samples can be taken over multiple timepoints from the same source, or can be from different environmentalsources (e.g., different animals).

The absolute abundance values over samples are used in one embodiment torelate the one or more active microorganism strains, with anenvironmental parameter (FIG. 2, 2008). In one embodiment, theenvironmental parameter is the presence of a second active microorganismstrain. Relating the one or more active microorganism strains to theenvironmental parameter, in one embodiment, is carried out bydetermining the co-occurrence of the strain and parameter by correlationor by network analysis.

In one embodiment, determining the co-occurrence of one or more activemicroorganism strains with an environmental parameter comprises anetwork and/or cluster analysis method to measure connectivity ofstrains or a strain with an environmental parameter within a network,wherein the network is a collection of two or more samples that share acommon or similar environmental parameter. In another embodiment, thenetwork and/or cluster analysis method may be applied to determining theco-occurrence of two or more active microorganism strains in a sample(FIG. 2, 2008). In another embodiment, the network analysis comprisesnonparametric approaches including mutual information to establishconnectivity between variables. In another embodiment, the networkanalysis comprises linkage analysis, modularity analysis, robustnessmeasures, betweenness measures, connectivity measures, transitivitymeasures, centrality measures or a combination thereof (FIG. 2, 2009).In another embodiment, the cluster analysis method comprises building aconnectivity model, subspace model, distribution model, density model,or a centroid model and/or using community detection algorithms such asthe Louvain, Bron-Kerbosch, Girvan-Newman, Clauset-Newman-Moore,Pons-Latapy, and Wakita-Tsurumi algorithms (FIG. 2, 2010).

In one embodiment, the cluster analysis method is a heuristic methodbased on modularity optimization. In a further embodiment, the clusteranalysis method is the Louvain method. See, e.g., the method describedby Blondel et al. (2008). Fast unfolding of communities in largenetworks. Journal of Statistical Mechanics: Theory and Experiment,Volume 2008, October 2008, incorporated by reference herein in itsentirety for all purposes.

In another embodiment, the network analysis comprises predictivemodeling of network through link mining and prediction, collectiveclassification, link-based clustering, relational similarity, or acombination thereof. In another embodiment, the network analysiscomprises differential equation based modeling of populations. Inanother embodiment, the network analysis comprises Lotka-Volterramodeling.

In one embodiment, relating the one or more active microorganism strainsto an environmental parameter (e.g., determining the co-occurrence) inthe sample comprises creating matrices populated with linkages denotingenvironmental parameter and microorganism strain associations.

In one embodiment, the multiple sample data obtained at step 2007 (e.g.,over two or more samples which can be collected at two or more timepoints where each time point corresponds to an individual sample), iscompiled. In a further embodiment, the number of cells of each of theone or more microorganism strains in each sample is stored in anassociation matrix (which can be in some embodiments, an abundancematrix). In one embodiment, the association matrix is used to identifyassociations between active microorganism strains in a specific timepoint sample using rule mining approaches weighted with association(e.g., abundance) data. Filters are applied in one embodiment to removeinsignificant rules.

In one embodiment, the absolute abundance of one or more, or two or moreactive microorganism strains is related to one or more environmentalparameters (FIG. 2, 2008), e.g., via co-occurrence determination.Environmental parameters are chosen by the user depending on thesample(s) to be analyzed and are not restricted by the methods describedherein. The environmental parameter can be a parameter of the sampleitself, e.g., pH, temperature, amount of protein in the sample.Alternatively, the environmental parameter is a parameter that affects achange in the identity of a microbial community (i.e., where the“identity” of a microbial community is characterized by the type ofmicroorganism strains and/or number of particular microorganism strainsin a community), or is affected by a change in the identity of amicrobial community. For example, an environmental parameter in oneembodiment, is the food intake of an animal or the amount of milk (orthe protein or fat content of the milk) produced by a lactating ruminantIn one embodiment, the environmental parameter is the presence, activityand/or abundance of a second microorganism strain in the microbialcommunity, present in the same sample.

In some embodiments described herein, an environmental parameter isreferred to as a metadata parameter.

Other examples of metadata parameters include but are not limited togenetic information from the host from which the sample was obtained(e.g., DNA mutation information), sample pH, sample temperature,expression of a particular protein or mRNA, nutrient conditions (e.g.,level and/or identity of one or more nutrients) of the surroundingenvironment/ecosystem), susceptibility or resistance to disease, onsetor progression of disease, susceptibility or resistance of the sample totoxins, efficacy of xenobiotic compounds (pharmaceutical drugs),biosynthesis of natural products, or a combination thereof.

For example, according to one embodiment, microorganism strain numberchanges are calculated over multiple samples according to the method ofFIG. 2 (i.e., at 2001-2007). Strain number changes of one or more activestrains over time is compiled (e.g., one or more strains that haveinitially been identified as active according to step 2006), and thedirectionality of change is noted (i.e., negative values denotingdecreases, positive values denoting increases). The number of cells overtime is represented as a network, with microorganism strainsrepresenting nodes and the abundance weighted rules representing edges.Markov chains and random walks are leveraged to determine connectivitybetween nodes and to define clusters. Clusters in one embodiment arefiltered using metadata in order to identify clusters associated withdesirable metadata (FIG. 2, 2008).

In a further embodiment, microorganism strains are ranked according toimportance by integrating cell number changes over time and strainspresent in target clusters, with the highest changes in cell numberranking the highest.

Network and/or cluster analysis method in one embodiment, is used tomeasure connectivity of the one or more strains within a network,wherein the network is a collection of two or more samples that share acommon or similar environmental parameter. In one embodiment, networkanalysis comprises linkage analysis, modularity analysis, robustnessmeasures, betweenness measures, connectivity measures, transitivitymeasures, centrality measures or a combination thereof. In anotherembodiment, network analysis comprises predictive modeling of networkthrough link mining and prediction, social network theory, collectiveclassification, link-based clustering, relational similarity, or acombination thereof. In another embodiment, network analysis comprisesdifferential equation based modeling of populations. In yet anotherembodiment, network analysis comprises Lotka-Volterra modeling.

Cluster analysis method comprises building a connectivity model,subspace model, distribution model, density model, or a centroid model.

Network and cluster based analysis, for example, to carry out methodstep 2008 of FIG. 2, can be carried out via a module. As used herein, amodule can be, for example, any assembly, instructions and/or set ofoperatively-coupled electrical components, and can include, for example,a memory, a processor, electrical traces, optical connectors, software(executing in hardware) and/or the like.

In some aspects, the present disclosure is drawn to administeringmicrobial compositions described herein to ruminants to improve one ormore traits through the modulation of aspects of milk production, milkquantity, milk quality, ruminant digestive chemistry, and efficiency offeed utilization and digestibility.

In some embodiments, improving the quantity of milk fat produced by aruminant is desirable, wherein milk fat includes triglycerides,triacylglycerides, diacylglycerides, monoacylglycerides, phospholipids,cholesterol, glycolipids, and free fatty acids. In further embodiments,free fatty acids include short chain fatty acids (i.e., C4:0, C6:0, andC8:0), medium chain fatty acids (i.e., C10:0, C10:1, C12:0, C14:0,C14:1, and C15:0), and long chain fatty acids (i.e., C16:0, C16:1,C17:0, C17:1, C18:0, C18:1, C18:2, C18:3, and C20:0). In furtherembodiments, it is desirable to achieve an increase in milk fatefficiency, which is measured by the total weight of milk fat produced,divided by the weight of feed ingested. The weight of milk fat producedis calculated from the measured fat percentage multiplied by the weightof milk produced.

In some embodiments, improving the quantity of carbohydrates in milkproduced by a ruminant is desirable, wherein carbohydrates includelactose, glucose, galactose, and oligosaccharides. Tao et al. (2009. J.Dairy Sci. 92:2991-3001) disclose numerous oligosaccharides that may befound in bovine milk.

In some embodiments, improving the quantity of proteins in milk producedby a ruminant, wherein proteins include caseins and whey. In someembodiments, proteins of interest are only those proteins produced inmilk. In other embodiments, proteins of interest are not required to beproduced only in milk. Whey proteins include immunoglobulins, serumalbumin, beta-lactoglobulin, and alpha-lactoglobulin.

In some embodiments, improving the quantity of vitamins in milk producedby a ruminant is desirable. Vitamins found in milk include thefat-soluble vitamins of A, D, E, and K; as well as the B vitamins foundin the aqueous phase of the milk.

In some embodiments, improving the quantity of minerals in milk producedby a ruminant is desirable.

Trace amounts of thefollowing may be found in milk: aluminum, arsenic, boron, bromine,cadmium, chromium, fluorine, iodine, lead, nickel, selenium, silicon,silver, strontium, and vanadium.

In some embodiments, improving the milk yield and milk volume producedby a ruminant is desirable. In some embodiments, it is further desirableif the increase in milk yield and volume is not accompanied by simply anincrease in solute volume.

In some embodiments improving energy-corrected milk (ECM) is desirable.In further embodiments, improving ECM amounts to increasing thecalculated ECM output. In some embodiments, the ECM is calculated asfollows: ECM=(0.327×milk pounds)+(12.95×fat pounds)+(7.2×proteinpounds).

It is thought that the microbial compositions modulate themicrobiome of the ruminants such that the biochemistry of the rumen ischanged in such a way that the ruminal liquid and solid substratum aremore efficiently and more completely degraded into subcomponents andmetabolites than the rumens of ruminants not having been administeredmicrobial compositions of the present disclosure.

In some embodiments, the increase in efficiency and the increase ofdegradation of the ruminal substratum result in an increase in improvedtraits of the present disclosure.

Mode of Action: Digestibility Improvement in Ruminants

The rumen is a specialized stomach dedicated to the digestion of feedcomponents in ruminants. A diverse microbial population inhabits therumen, where their primary function revolves around converting thefibrous and non-fibrous carbohydrate components into useable sources ofenergy and protein (FIG. 16). Cellulose, in particular, forms up to 40%of plant biomass and is considered indigestible by mammals. It also istightly associated with other structural carbohydrates, includinghemicellulose, pectin, and lignin. The cellulolytic microbes in therumen leverage extensive enzymatic activity in order break thesemolecules down into simple sugars and volatile fatty acids. Thisenzymatic activity is critical to the extraction of energy from feed,and more efficient degradation ultimately provides more energy to theanimal. The soluble sugars found in the non-fibrous portion of the feedare also fermented into gases and volatile fatty acids such as butyrate,propionate, and acetate. Volatile fatty acids arising from the digestionof both the fibrous and non-fibrous components of feed are ultimatelythe main source of energy of the ruminant.

Individual fatty acids have been tested in ruminants in order toidentify their impacts on varying aspects of production.

Acetate:

Structural carbohydrates produce large amounts of acetate when degraded.An infusion of acetate directly into the rumen was shown to improve theyield of milk, as well as the amount of milk fat produced. Acetaterepresents at least 90% of acids in the peripheral blood—it is possiblethat acetate can be directly utilized by mammary tissue as a source ofenergy. See Rook and Balch. 1961. Brit. J. Nutr. 15:361-369.

Propionate:

Propionate has been shown to increase milk protein production, butdecrease milk yield. See Rook and Balch. 1961. Brit. J. Nutr.15:361-369.

Butyrate:

An infusion of butyrate directly into the rumen of dairy cows increasesmilk fat production without changing milk yield. See Huhtanen et al.1993. J. Dairy Sci. 76:1114-1124.

Network Analysis

A network and/or cluster analysis method, in one embodiment, is used tomeasure connectivity of the one or more strains within a network,wherein the network is a collection of two or more samples that share acommon or similar environmental parameter. In one embodiment, networkanalysis comprises linkage analysis, modularity analysis, robustnessmeasures, betweenness measures, connectivity measures, transitivitymeasures, centrality measures or a combination thereof. In anotherembodiment, network analysis comprises predictive modeling of networkthrough link mining and prediction, social network theory, collectiveclassification, link-based clustering, relational similarity, or acombination thereof. In another embodiment, network analysis comprisesmutual information, maximal information coefficient (MIC) calculations,or other nonparametric methods between variables to establishconnectivity. In another embodiment, network analysis comprisesdifferential equation based modeling of populations. In yet anotherembodiment, network analysis comprises Lotka-Volterra modeling.

The environmental parameter can be a parameter of the sample itself,e.g., pH, temperature, amount of protein in the sample. Alternatively,the environmental parameter is a parameter that affects a change in theidentity of a microbial community (i.e., where the “identity” of amicrobial community is characterized by the type of microorganismstrains and/or number of particular microorganism strains in acommunity), or is affected by a change in the identity of a microbialcommunity. For example, an environmental parameter in one embodiment, isthe food intake of an animal or the amount of milk (or the protein orfat content of the milk) produced by a lactating ruminant In oneembodiment, the environmental parameter is the presence, activity and/orabundance of a second microorganism strain in the microbial community,present in the same sample. In some embodiments, an environmentalparameter is referred to as a metadata parameter.

Other examples of metadata parameters include but are not limited togenetic information from the host from which the sample was obtained(e.g., DNA mutation information), sample pH, sample temperature,expression of a particular protein or mRNA, nutrient conditions (e.g.,level and/or identity of one or more nutrients) of the surroundingenvironment/ecosystem), susceptibility or resistance to disease, onsetor progression of disease, susceptibility or resistance of the sample totoxins, efficacy of xenobiotic compounds (pharmaceutical drugs),biosynthesis of natural products, or a combination thereof.

EXAMPLES Example I. Increase Total Milk Fat, Milk Protein, andEnergy-Corrected Milk (ECM) in Cows

The methods of Example I aim to increase the total amount of milk fatand milk protein produced by a lactating ruminant, and the calculatedECM.

The methodologies presented herein—based upon utilizing the disclosedisolated microbes, consortia, and compositions comprising thesame—demonstrate an increase in the total amount of milk fat and milkprotein produced by a lactating ruminant. These increases were realizedwithout the need for further addition of hormones.

In this example, a microbial consortium comprising two isolatedmicrobes, Ascusb_3138 (SEQ ID NO:28; deposited as NRRL Y-67248) andAscusf_15 (SEQ ID NO:32; deposited as NRRL Y67249), was administered toHolstein cows in mid-stage lactation over a period of five weeks.

The cows were randomly assigned into 2 groups of 8, wherein one of thegroups was a control group that received a buffer lacking a microbialconsortium. The second group, the experimental group, was administered amicrobial consortium comprising Ascusb_3138 (SEQ ID NO:28) and Ascusf_15(SEQ ID NO:32) once per day for five weeks. Each of the cows were housedin individual pens and were given free access to feed and water. Thediet was a high milk yield diet. Cows were fed ad libitum and the feedwas weighed at the end of the day, and prior day refusals were weighedand discarded. Weighing was performed with a PS-2000 scale from SalterBrecknell (Fairmont, Minn.).

Cows were cannulated such that a cannula extended into the rumen of thecows. Cows were further provided at least 10 days of recovery postcannulation prior to administering control dosages or experimentaldosages.

Each administration consisted of 20 ml of a neutral buffered saline, andeach administration consisted of approximately 10⁹ cells suspended inthe saline. The control group received 20 ml of the saline once per day,while the experimental group received 20 ml of the saline furthercomprising 10⁹ microbial cells of the described microbial consortium.

The rumen of every cow was sampled on days 0, 7, 14, 21, and 35, whereinday 0 was the day prior to microbial administration. Note that theexperimental and control administrations were performed after the rumenwas sampled on that day. Daily sampling of the rumen, beginning on day0, with a pH meter from Hanna Instruments (Woonsocket, R.I.) wasinserted into the collected rumen fluid for recordings. Rumen samplingincluded both particulate and fluid sampling from the center, dorsal,ventral, anterior, and posterior regions of the rumen through thecannula, and all five samples were pooled into 15 ml conical vialscontaining 1.5 ml of stop solution (95% ethanol, 5% phenol). A fecalsample was also collected on each sampling day, wherein feces werecollected from the rectum with the use of a palpation sleeve. Cows wereweighed at the time of each sampling.

Fecal samples were placed in a 2 ounce vial, stored frozen, and analyzedto determine values for apparent neutral detergent fibers (NDF)digestibility, apparent starch digestibility, and apparent proteindigestibility. Rumen sampling consisted of sampling both fluid andparticulate portions of the rumen, each of which was stored in a 15 mlconical tube. Cells were fixed with a 10% stop solution (5% phenol/95%ethanol mixture) and kept at 4° C. and shipped to Ascus Biosciences(Vista, Calif.) on ice.

The milk yield was measured twice per day, once in the morning and onceat night. Milk composition (% fats and % proteins, etc.) was measuredtwice per day, once in the morning and once at night. Milk samples werefurther analyzed with near-infrared spectroscopy for protein fats,solids, analysis for milk urea nitrogen (MUN), and somatic cell counts(SCC) at the Tulare Dairy Herd Improvement Association (DHIA) (Tulare,Calif.). Feed intake of individual cows and rumen pH were determinedonce per day.

A sample of the total mixed ration (TMR) was collected the final day ofthe adaptation period, and then successively collected once per week.Sampling was performed with the quartering method, wherein the sampleswere stored in vacuum sealed bags which were shipped to CumberlandValley Analytical Services (Hagerstown, Md.) and analyzed with the NIR1package.

Table 12 reveals the effects of daily administration of an Ascusmicrobial consortium on the performance of multiparous Holstein cows(between 60 and 120 days in milk). Marked differences between thecontrol and inoculated treatments were observed. The inoculated groupexperienced increases in all parameters except FCM/DMI and rumen pH. Theweekly values at the beginning of the intervention period when cows werestill adapting to the treatment are included in the calculations.

FIGS. 4-7 demonstrate the significant effects of the microbial consortiaon dairy cows for daily milk yield, daily milk crude protein yield,daily milk fat yield, and daily energy corrected milk yield over time.After an initial adaptation period, during which the microbes wereobserved to colonize the rumen, the production characteristics of theinoculated treatment group increased and diverged from the controlgroup.

FIG. 3A demonstrates that cows that were administered the microbialconsortia exhibited a 20.9% increase in the average production of milkfat versus cows that were administered the buffered solution alone. FIG.3B demonstrates that cows that were administered the microbial consortiaexhibited a 20.7% increase in the average production of milk proteinversus cows that were administered the buffered solution alone. FIG. 3Cdemonstrates that cows that were administered the microbial consortiaexhibited a 19.4% increase in the average production of energy correctedmilk. The increases seen in FIG. 3A-C became less pronounced after theadministration of the consortia ceased, as depicted by the vertical lineintersecting the data points.

FIG. 14 clearly identifies the effect of microbial consortia on thesomatic cell count in the milk. The experimental group of cows receivingthe microbial consortia exhibited a decrease in the number of cows withgreater than 200,000 somatic cells/ml of milk. In the field of dairyfarming, the SCC is a strong indicator of milk quality. The majority ofsomatic cells found in milk are leukocytes, immune cells that accumulatein a particular tissue/fluid in increasing numbers usually due to animmune response to a pathogen. Generally, the lower the SCC the higherthe quality of milk. Dosogne et al. 2011. J. Dairy Sci. 86(3):828-834.

Consortium 14—Ascusb_3138 and Ascusf_15.

The cows are randomly assigned into 15 groups of 8, wherein one of thegroups is a control group that receives a buffer lacking a microbialconsortium. The remaining seven groups are experimental groups and willeach be administered one of the thirteen microbial bioconsortia once perday for six weeks. Each of the cows are held in individual pens tomitigate cross-contamination and are given free access to feed andwater. The diet is a high milk yield diet. Cows are fed twice per dayand the feed will be weighed at each feeding, and prior day refusalswill be weighed and discarded. Weighing is performed with a PS-2000scale from Salter Brecknell (Fairmont, Minn.).

Cows are cannulated such that a cannula extends into the rumen of thecows. Cows are further provided at least 10 days of recovery postcannulation prior to administering control dosages or experimentaldosages.

Each administration consists of 5 ml of a neutral buffered saline, andeach administration consists of approximately 10⁹ cells suspended in thesaline. The control group receives 5 ml of the saline once per day,while the experimental groups receive 5 ml of the saline furthercomprising 10⁹ microbial cells of the described consortia.

The rumen of every cow is sampled on days 0, 7, 14, 21, and 35, whereinday 0 is the day prior to microbial administration. Note that theexperimental and control administrations are performed after the rumenhas been sampled on that day. Daily sampling of the rumen, beginning onday 0, with a pH meter from Hanna Instruments (Woonsocket, R.I.) isinserted into the collected rumen fluid for recordings. Rumen samplingincluded both particulate and fluid sampling from the center, dorsal,ventral, anterior, and posterior regions of the rumen through thecannula, and all five samples were pooled into 15 ml conical vialscontaining 1.5 ml of stop solution (95% ethanol, 5% phenol). A fecalsample is also collected on each sampling day, wherein feces arecollected from the rectum with the use of a palpation sleeve. Cows areweighed at the time of each sampling.

Fecal samples are placed in a 2 ounce vial, stored frozen, and analyzedto determine values for apparent NDF digestibility, apparent starchdigestibility, and apparent protein digestibility. Rumen samplingconsists of sampling both fluid and particulate portions of the rumen,each of which is stored in a 15 ml conical tube. Cells are fixed with a10% stop solution (5% phenol/95% ethanol mixture) and kept at 4° C. andshipped to Ascus Biosciences (Vista, Calif.) on ice.

The milk yield is measured twice per day, once in the morning and onceat night. Milk composition (% fats and % proteins, etc.) is measuredtwice per day, once in the morning and once at night. Milk samples arefurther analyzed with near-infrared spectroscopy for protein fats,solids, analysis for milk urea nitrogen (MUN), and somatic cell counts(SCC) at the Tulare Dairy Herd Improvement Association (DHIA) (Tulare,Calif.). Feed intake of individual cows and rumen pH are determined onceper day.

A sample of the total mixed ration (TMR) is collected the final day ofthe adaptation period, and then successively collected once per week.Sampling is performed with the quartering method, wherein the samplesare stored in vacuum sealed bags which are shipped to Cumberland ValleyAnalytical Services (Hagerstown, Md.) and analyzed with the NIR1package.

In some embodiments, the percent fats and percent protein of milk ineach of the experimental cow groups is expected to demonstrate astatistically significant increase over the percent fats and percentprotein of milk in the control cow group. In other embodiments, theincrease is not expected to be statistically significant, but it isexpected to be still quantifiable.

Example III. Shifting the Microbiome of Ruminants

In certain embodiments of the disclosure, the present methods aim tomodulate the microbiome of ruminants through the administration of oneor more microbes to the gastrointestinal tract of ruminants.

The methodologies presented herein—based upon utilizing the disclosedisolated microbes, consortia, and compositions comprising the same—havethe potential to modulate the microbiome of ruminants. The modulation ofa ruminant's gastrointestinal microbiome may lead to an increase ofdesirable traits of the present disclosure.

In this example, the microbial consortia of Table 5 are administered toHolstein cows over a period of six weeks.

The cows are randomly assigned into 37 groups of 8, wherein one of thegroups is a control group that receives a buffer lacking a microbialconsortium. The remaining thirty-six groups are experimental groups andwill each be administered one of the thirty-six microbial consortia onceper day for six weeks. Each of the cows are held in individual pens tomitigate cross-contamination and are given free access to feed andwater. The diet is a high milk yield diet. Cows are fed twice per dayand the feed will be weighed at each feeding, and prior day refusalswill be weighed and discarded. Weighing is performed with a PS-2000scale from Salter Brecknell (Fairmont, Minn.).

Cows are cannulated such that a cannula extends into the rumen of thecows. Cows are further provided at least 10 days of recovery postcannulation prior to administering control dosages or experimentaldosages.

Each administration consists of 5 ml of a neutral buffered saline, andeach administration consists of approximately 10⁹ cells suspended in thesaline. The control group receives 5 ml of the saline once per day,while the experimental groups receive 5 ml of the saline furthercomprising 10⁹ microbial cells of the described consortia.

The rumen of every cow is sampled on days 0, 7, 14, 21, and 35, whereinday 0 is the day prior to administration. Note that the experimental andcontrol administrations are performed after the rumen has been sampledon that day. Daily sampling of the rumen, beginning on day 0, with a pHmeter from Hanna Instruments (Woonsocket, R.I.) is inserted into thecollected rumen fluid for recordings. Rumen sampling included bothparticulate and fluid sampling from the center, dorsal, ventral,anterior, and posterior regions of the rumen through the cannula, andall five samples were pooled into 15 ml conical vials containing 1.5 mlof stop solution (95% ethanol, 5% phenol). A fecal sample is alsocollected on each sampling day, wherein feces are collected from therectum with the use of a palpation sleeve. Cows are weighed at the timeof each sampling.

Fecal samples are placed in a 2 ounce vial, stored frozen, and analyzedto determine values for apparent NDF digestibility, apparent starchdigestibility, and apparent protein digestibility. Rumen samplingconsists of sampling both fluid and particulate portions of the rumen,each of which is stored in a 15 ml conical tube. Cells are fixed with a10% stop solution (5% phenol/95% ethanol mixture) and kept at 4° C. andshipped to Ascus Biosciences (Vista, Calif.) on ice.

The samples of fluid and particulate portions of the rumen, as well asthe fecal samples are each evaluated for microbiome fingerprintingutilizing the T-RFLP method combined with nMDS ordination and PERMANOVAstatistics.

In some embodiments, the ruminal and fecal microbiome in each of theexperimental cow groups is expected to demonstrate a statisticallysignificant change in the microbiomes over the microbiomes in thecontrol cow group as well as the 0 day microbiome samples, wherein thechange is a significant increase in the proportion of microbesadministered in the experimental administrations. In other embodiments,the increase is not expected to be statistically significant, but it isexpected to be still quantifiable.

Example IV. Milk Fat Produced Versus Absolute Abundance of Microbes

Determine rumen microbial community constituents that impact theproduction of milk fat in dairy cows.

Eight lactating, ruminally cannulated, Holstein cows were housed inindividual tie-stalls for use in the experiment. Cows were fed twicedaily, milked twice a day, and had continuous access to fresh water. Onecow (cow 4201) was removed from the study after the first dietary MilkFat Depression due to complications arising from an abortion prior tothe experiment.

Experimental Design and Treatment:

The experiment used a crossover design with 2 groups and 1 experimentalperiod. The experimental period lasted 38 days: 10 days for thecovariate/wash-out period and 28 days for data collection and sampling.The data collection period consisted of 10 days of dietary Milk FatDepression (MFD) and 18 days of recovery. After the first experimentalperiod, all cows underwent a 10-day wash out period prior to thebeginning of period 2.

Dietary MFD was induced with a total mixed ration (TMR) low in fiber(29% NDF) with high starch degradability (70% degradable) and highpolyunsaturated fatty acid levels (PUFA, 3.7%). The Recovery phaseincluded two diets variable in starch degradability. Four cows wererandomly assigned to the recovery diet high in fiber (37% NDF), low inPUFA (2.6%), and high in starch degradability (70% degradable). Theremaining four cows were fed a recovery diet high in fiber (37% NDF),low in PUFA (2.6%), but low in starch degradability (35%).

During the 10-day covariate and 10-day wash out periods, cows were fedthe high fiber, low PUFA, and low starch degradability diet.

Samples and Measurements:

Milk yield, dry matter intake, and feed efficiency were measured dailyfor each animal throughout the covariate, wash out, and samplecollection periods. TMR samples were measured for nutrient composition.During the collection period, milk samples were collected and analyzedevery 3 days. Samples were analyzed for milk component concentrations(milk fat, milk protein, lactose, milk urea nitrogen, somatic cellcounts, and solids) and fatty acid compositions.

Rumen samples were collected and analyzed for microbial communitycomposition and activity every 3 days during the collection period. Therumen was intensively sampled 0, 2, 4, 6, 8, 10, 12, 14, 16, 18, 20, and22 hours after feeding during day 0, day 7, and day 10 of the dietaryMFD. Similarly, the rumen was intensively sampled 0, 2, 4, 6, 8, 10, 12,14, 16, 18, 20, and 22 hours after feeding on day 16 and day 28 of thesample collection period. Rumen contents were analyzed for pH, acetateconcentration, butyrate concentration, propionate concentration, isoacidconcentration, and long chain and CLA isomer concentrations. Rumensampling included both particulate and fluid sampling from the center,dorsal, ventral, anterior, and posterior regions of the rumen throughthe cannula, and all five samples were pooled into 15 ml conical vials.

Rumen Sample Preparation and Sequencing:

After collection, rumen samples were centrifuged at 4,000 rpm in a swingbucket centrifuge for 20 minutes at 4° C. The supernatant was decanted,and an aliquot of each rumen content sample (1-2 mg) was added to asterile 1.7 mL tube prefilled with 0.1 mm glass beads. A second aliquotwas collected and stored in an empty, sterile 1.7 mL tube for cellcounting.

Rumen samples in empty tubes were stained and put through a flowcytometer to quantify the number of cells of each microorganism type ineach sample. Rumen samples with glass beads were homogenized with beadbeating to lyse microorganisms. DNA and RNA was extracted and purifiedfrom each sample and prepared for sequencing on an Illumina Miseq.Samples were sequenced using paired-end chemistry, with 300 base pairssequenced on each end of the library.

Sequencing Read Processing and Data Analysis:

Sequencing reads were quality trimmed and processed to identifybacterial species present in the rumen based on a marker gene, 16S rDNA,or ITS1 and/or ITS2. Count datasets and activity datasets wereintegrated with the sequencing reads to determine the absolute cellnumbers of active microbial species within the rumen microbialcommunity. Production characteristics of the cow over time, includingpounds of milk produced, were linked to the distribution of activemicroorganisms within each sample over the course of the experimentusing mutual information.

Tests cases to determine the impact of count data, activity data, andcount and activity on the final output were run by omitting theappropriate datasets from the sequencing analysis. To assess the impactof using a linear correlation rather than the MIC on target selection,Pearson's coefficients were also calculated for pounds of milk fatproduced as compared to the relative abundance of all microorganisms andthe absolute abundance of active microorganisms.

Results

One component of the Ascus Biosciences technology utilized in thisapplication leverages mutual information to rank the importance ofnative microbial strains residing in the gastrointestinal tract of theanimal to specific animal traits. The maximal information coefficient(MIC) scores are calculated for all microorganisms and the desiredanimal trait. Relationships were scored on a scale of 0 to 1, with 1representing a strong relationship between the microbial strain and theanimal trait, and 0 representing no relationship. A cut-off based onthis score is used to define useful and non-useful microorganisms withrespect to the improvement of specific traits. FIG. 9 and FIG. 10 depictthe MIC score distribution for rumen microbial strains that share arelationship with milk fat efficiency in dairy cows. The point where thecurve shifts from exponential to linear (˜0.45-0.5 for bacteria and ˜0.3for fungi) represents the cutoff between useful and non-usefulmicroorganism strains pertaining to milk fat efficiency. FIG. 11 andFIG. 12 depict the MIC score distributions for rumen microbial strainsthat share a relationship with dairy efficiency. The point where thecurve shifts from exponential to linear (˜0.45-0.5 for bacteria and˜0.25 for fungi) represents the cutoff between useful and non-usefulmicroorganism strains.

The MICs were calculated between pounds of milk fat produced and theabsolute abundance of each active microorganism. Microorganisms wereranked by MIC score, and microorganisms with the highest MIC scores wereselected as the target species most relevant to pounds of milk produced.MIC scores of the microbes of the present disclosure are recited inTable 1. The greater the MIC score, the greater the ability of themicrobe to confer an increase in the weight of milk fat produced by acow

Example V. Comparative Analysis of MIC Scores from Published Work ofOther Groups

Utilizing Ascus Biosciences' technology, the performance of currentlyavailable microbial feed additive products was predicted.

Direct-fed microbial products that claim to enhance dairy performanceare openly available on the market. Some of these products containmicroorganism strains that are native rumen microorganisms (Megasphaeraelsdenii), or are within 97% sequence similarity of native rumenmicroorganisms. We have identified the species of microbes utilized inthese products, and calculated their MIC score with respect to milk fatefficiency (FIG. 13). As evidenced by the curve in FIG. 13, all of theassayed strains that were available fell below the threshold used todefine useful and non-useful strains, as describe above. Thespecies/strain closest to the cutoff, Prevotella bryantii, has shown apositive effect in one study.

Lactobacillus plantarum: MIC 0.28402

The calculated MIC predicts that Lactobacillus plantarum is poorlyassociated with milk fat efficiency, and the art discloses that aninoculation of L. plantarum yields no increase in milk fat product, andat least one study discloses that some strains of L. plantarum createmolecules that cause milk fat depression. See Lee et al. 2007. J. Appl.Microbiol. 103(4):1140-1146 and Mohammed et al. 2012. J. Dairy Sci.95(1):328-339.

Lactobacillus acidophilus: MIC 0.30048

The calculated MIC predicts that Lactobacillus acidophilus is poorlyassociated with milk fat efficiency, and the art discloses that theadministration of L. acidophilus to dairy cows/calves had no effect ofvarious aspects of milk yield/milk component yield. See Higginbotham andBath. 1993. J. Dairy Sci. 76(2):615-620; Abu-Tarboush et al. 1996.Animal Feed Sci. Tech. 57(1-2):39-49; McGilliard and Stallings. 1998. J.Dairy Sci. 81(5):1353-1357; and Raeth-Knight et al. 2007. J. Dairy Sci.90(4):1802-1809; But see Boyd et al. 2011. 94(9):4616-4622 (discloses anincrease in milk yield and milk protein yield). While Boyd et al. doesdisclose an increase in milk and milk protein yield, the controls ofthis single study do not appear to adequately isolate the presence of L.acidophilus as the cause of the increase. The body of prior artcontradicts the finding of Boyd et al.

Megasphaera elsdenii: MIC 0.32548

The calculated MIC predicts that Megasphaera elsdenii is poorlyassociated with milk fat efficiency, and the art provides substantialevidence to suggest that Megasphaera elsdenii has no positive effectupon milk fat efficiency, but multiple references provide evidence tosuggest that it has a negative effect on milk fat efficiency. See Kim etal. 2002. J. Appl. Micro. 92(5):976-982; Hagg. 2008. Dissertation,University of Pretoria. 1-72; Hagg et al. 2010. S. African. J. AnimalSci. 40(2):101-112; Zebeli et al. 2011. J.

Animal Sci.Poster Abstract. 94(sup. 5):784.

Prevotella bryantii: MIC 0.40161

The calculated MIC predicts that Prevotella bryantii is not highlyassociated with milk fat efficiency, and the art provides evidence thatP. bryantii administered during subacute acidosis challenge inmidlactation dairy cows has no apparent effect on milk yield, whereasadministration of the microbe to dairy cows in early lactation yieldsimproved milk fat concentrations. See Chiquette et al. 2012. J. DairySci. 95(10):5985-5995, but see Chiquette et al. 2008. 91(9):3536-3543;respectively.

Example VI. Shift in Rumen Microbial Composition After Administration ofa Microbial Composition

The methods of the instant example aim to increase the total amount ofmilk fat and milk protein produced by a lactating ruminant, and thecalculated energy corrected milk (ECM).

The methodologies presented herein—based upon utilizing the disclosedisolated microbes, consortia, and compositions comprising thesame—demonstrate an increase in the total amount of milk fat and milkprotein produced by a lactating ruminant. These increases were realizedwithout the need for further addition of hormones.

In this example, a microbial consortium comprising two isolatedmicrobes, Ascusb_3138 (SEQ ID NO:28) and Ascusf_15 (SEQ ID NO:32), wasadministered to Holstein cows in mid-stage lactation over a period offive weeks.

The cows were randomly assigned into 2 groups of 8, in which one of thegroups was a control group that received a buffer lacking a microbialconsortium. The second group, the experimental group, was administered amicrobial consortium comprising Ascusb_3138 (SEQ ID NO:28) and Ascusf_15(SEQ ID NO:32) once per day for five weeks. Each cow was housed in anindividual pen and was given free access to feed and water. The diet wasa high milk yield diet. Cows were fed ad libitum and the feed wasweighed at the end of each day, and prior day refusals were weighed anddiscarded. Weighing was performed with a PS-2000 scale from SalterBrecknell (Fairmont, Minn.).

Cows were cannulated such that a cannula extended into the rumen of thecows. Cows were further provided at least 10 days of recovery postcannulation prior to administering control dosages or experimentaldosages.

Each administration consisted of 20 ml of a neutral buffered saline, andeach administration consisted of approximately 10⁹ cells suspended inthe saline. The control group received 20 ml of the saline once per day,while the experimental group received 20 ml of the saline furthercomprising 10⁹ microbial cells of the described microbial consortium.

The rumen of every cow was sampled on days 0, 7, 14, 21, and 35, whereinday 0 was the day prior to microbial administration. Note that theexperimental and control administrations were performed after the rumenwas sampled on that day. Daily sampling of the rumen, beginning on day0, with a pH meter from Hanna Instruments (Woonsocket, R.I.) wasinserted into the collected rumen fluid for recordings. Rumen samplingincluded both particulate and fluid sampling from the center, dorsal,ventral, anterior, and posterior regions of the rumen through thecannula, and all five samples were pooled into 15 ml conical vialscontaining 1.5 ml of stop solution (95% ethanol, 5% phenol) and storedat 4° C. and shipped to Ascus Biosciences (Vista, Calif.) on ice.

A portion of each rumen sample was stained and put through a flowcytometer to quantify the number of cells of each microorganism type ineach sample. A separate portion of the same rumen sample was homogenizedwith bead beating to lyse microorganisms. DNA and RNA was extracted andpurified from each sample and prepared for sequencing on an IlluminaMiseq. Samples were sequenced using paired-end chemistry, with 300 basepairs sequenced on each end of the library. The sequencing reads wereused to quantify the number of cells of each active, microbial memberpresent in each animal rumen in the control and experimental groups overthe course of the experiment.

Ascusb_3138 and Ascusf_15 both colonized, and were active in the rumenafter ˜3-5 days of daily administration, depending on the animal. Thiscolonization was observed in the experimental group, but not in thecontrol group. The rumen is a dynamic environment, where the chemistryof the cumulative rumen microbial population is highly intertwined. Theartificial addition of Ascusb_3138 and Ascuf_15 could have effects onthe overall structure of the community. To assess this potential impact,the entire microbial community was analyzed over the course of theexperiment to identify higher level taxonomic shifts in microbialcommunity population.

Distinct trends were not observed in the fungal populations over time,aside from the higher cell numbers of Ascusf_15 in the experimentalanimals. The bacterial populations, however, did change morepredictably. To assess high level trends across individual animals overtime, percent compositions of the microbial populations were calculatedand compared. See

Table 13.

Only genera composing greater than 1% of the community were analyzed.The percent composition of genera containing known fiber-degradingbacteria, including Ruminococcus, was found to increase in experimentalanimals as compared to control animals. Volatile fatty acid-producinggenera, including Clostridial cluster XIVa, Clostridium,Pseudobutyrivibrio, Butyricimonas, and Lachnospira were also found athigher abundances in the experimental animals. The greatest shift wasobserved in the genera Prevotella. Members of this genus have been shownto be involved in the digestion of cellobiose, pectin, and various otherstructural carbohydrates within the rumen. Prevotella sp. have furtherbeen implicated in the conversion of plant lignins into beneficialantioxidants (Schogor et al. PLOS One. 9(4):e87949 (10 p.)).

To more directly measure quantitative changes in the rumen over time,cell count data was integrated with sequencing data to identify bulkchanges in the population at the cell level. Fold changes in cellnumbers were determined by dividing the average number of cells of eachgenera in the experimental group by the average number of cells of eachgenera in the control group. See Table 13. The cell count analysiscaptured many genera that fell under the threshold in the previousanalysis Promicromonospora, Rhodopirellula, Olivibacter, Victivallis,Nocardia, Lentisphaera, Eubacteiru, Pedobacter, Butyricimonas,Mogibacterium, and Desulfovibrio were all found to be at least 10 foldhigher on average in the experimental animals. Prevotella, Lachnospira,Butyricicoccus, Clostridium XIVa, Roseburia, Clostridium_sensu_stricto,and Pseudobutyrivibrio were found to be ˜1.5 times higher in theexperimental animals.

To assess the ability of the strains to produce volatile fatty acids,High Performance Liquid Chromatography (HPLC) was utilized to measurethe concentration of acetate, butyrate, and propionate in spent media.M2GSC media was used in an assay mimicking rumen conditions as closelyas possible.

For pure cultures, a single colony from each of the desired strains(from anaerobic agar plates) was inoculated into M2GSC media. A mediumblank (control) was also prepared. Cultures and the medium blank wereincubated at 37° C. until significant growth was visible. An opticaldensity (OD600) was determined for each culture, and the strain ID wasconfirmed with Illumina sequencing. An aliquot of culture was subjectedto sterile filtration into a washed glass 15 ml sample vial and analyzedby HPLC; HPLC assays were performed at Michigan State University.Enrichments that exhibited growth were also stained and cell counted toconfirm that the individual strains within each enrichment grew. Strainsoften appeared in multiple enrichments, so the enrichment with thehighest amount of growth for the strain (i.e. the highest increase incell number of that strain) is reported in Table 15.

Due to the vast complexity of metabolisms and microbial lifestylespresent in the rumen, many rumen microorganisms are incapable of axenicgrowth. In order to assay these organisms for desirable characteristics,enrichments cultures were established under a variety of conditions thatmimicked particular features of the rumen environment. Diluted rumenfluid (1/100 dilution) was inoculated into M2GSC or M2 mediasupplemented with a variety of carbon sources including xylose (4 g/L),mannitol (4 g/L), glycerol (4 g/L), xylan (2 g/L), cellobiose (2 g/L),arabinose (4 g/L), mannose (4 g/L), rhaminose (2 g/L), maltose (2 g/L),maltose (2 g/L), and molasses. Rumen fluid was also sometimes omittedfrom the recipe. Additions including amino acids, volatile fatty acids,and antibiotics, were also varied across the enrichments. A medium blank(control) was also prepared. Cultures and the medium blank wereincubated at 37° C. until significant growth was visible. An opticaldensity (OD600) was determined for each culture, and the strain IDs wereconfirmed with Illumina sequencing. An aliquot of culture was subjectedto sterile filtration into a washed glass 15 ml sample vial and analyzedby HPLC; HPLC assays were performed at Michigan State University.Enrichments that exhibited growth were also stained and cell counted toconfirm that the individual strains within each enrichment grew. Strainsoften appeared in multiple enrichments, so the enrichment with thehighest amount of growth for the strain (i.e, the highest increase incell number of that strain) is reported in Table 15.

Concentrations of acetate, butyrate, and propionate were quantified forthe medium blanks as well as the sterile filtered culture samples forboth pure strain and enrichment experiments. HPLC parameters were asfollows: Biorad Aminex HPX-87H column, 60° C., 0.5 ml/minute mobilephase 0.00325 N H₂l SO₄, 500 psi, 35C RI detector, 45 minute run time,and 5 μL injection volume. Concentrations of acetate, butyrate, andpropionate for both pure cultures and enrichments are reported in Table15.

Soluble Carbon Source Assay

To assess the ability of the strains to degrade various carbon sources,an optical density (OD600) was used to measure growth of strains onmultiple carbon sources over time.

For pure isolates, a single colony from each of the desired strains(from anaerobic agar plates) was inoculated into M2GSC media. A mediumblank (control) was also prepared. Strains were inoculated into a carbonsource assay anaerobically, wherein the assay was set up in a 2 mLsterile 96-well plate, with each well containing RAMM salts, vitamins,minerals, cysteine, and a single carbon source. Carbon sources includedglucose, xylan, lactate, xylose, mannose, glycerol, pectin, molasses,and cellobiose. Cells were inoculated such that each well started at anOD600 of 0.01. Optican densities were read at 600 nm with the Synergy H4hybrid plate reader. The strain IDs were confirmed with Illuminasequencing after all wells were in stationary phase.

As in the volatile fatty acid assay above, enrichments were also used toassay carbon source degradation. Diluted rumen fluid (1/100 dilution)was inoculated into M2GSC or M2 media supplemented with a variety ofcarbon sources including xylose (4 g/L), mannitol (4 g/L), glycerol (4g/L), xylan (2 g/L), cellobiose (2 g/L), arabinose (4 g/L), mannose (4g/L), rhaminose (2 g/L), maltose (2 g/L), maltose (2 g/L), and molasses.Rumen fluid was also sometimes omitted from the recipe. Additionsincluding amino acids, volatile fatty acids, and antibiotics, were alsovaried across the enrichments. A medium blank (control) was alsoprepared. Cultures and the medium blank were incubated at 37° C. untilsignificant growth was visible. An optical density (OD600) wasdetermined for each culture, and the strain IDs were confirmed withIllumina sequencing. Enrichments that exhibited growth were also stainedand cell counted to confirm that the individual strains within eachenrichment grew.

C. Insoluble Carbon Source Assay

To assess the ability of the strains to degrade insoluble carbonsources, visual inspection was leveraged to qualitatively determine astrain's degradation capabilities.

For pure cultures, a single colony from each of the desired strains(from anaerobic agar plates) was inoculated into anaerobic Hungate tubescontaining Lowe's semi defined media with cellulose paper, starch, orgrass as the sole carbon source. (Lowe et al. 1985. J. Gen. Microbiol.131:2225-2229). Enrichment cultures using a 1/100 dilution of rumenfluid were also set up using the same medium conditions. Cultures werechecked visually for degradation of insoluble carbon sources (See FIG.14). Strain ID was confirmed using Illumina sequencing. Enrichments thatexhibited growth were also stained and cell counted to confirm that theindividual strains within each enrichment grew.

Example VIII. Determination of Maximal Information Coefficient (MIC)Scores for Microbe Strains Relevant to Pounds of Milk Produced

Experimental Design and Materials and Methods

Objective:

Determine rumen microbial community constituents that impact theproduction of milk fat in dairy cows.

Animals:

Eight lactating, ruminally cannulated, Holstein cows were housed inindividual tie-stalls for use in the experiment. Cows were fed twicedaily, milked twice a day, and had continuous access to fresh water. Onecow (cow 1) was removed from the study after the first dietary Milk FatDepression due to complications arising from an abortion prior to theexperiment.

Experimental Design and Treatment:

The experiment used a crossover design with 2 groups and 1 experimentalperiod. The experimental period lasted 38 days: 10 days for thecovariate/wash-out period and 28 days for data collection and sampling.The data collection period consisted of 10 days of dietary Milk FatDepression (MFD) and 18 days of recovery. After the first experimentalperiod, all cows underwent a 10-day wash out period prior to thebeginning of period 2.

Dietary MFD was induced with a total mixed ration (TMR) low in fiber(29% NDF) with high starch degradability (70% degradable) and highpolyunsaturated fatty acid levels (PUFA, 3.7%). The Recovery phaseincluded two diets variable in starch degradability. Four cows wererandomly assigned to the recovery diet high in fiber (37% NDF), low inPUFA (2.6%), and high in starch degradability (70% degradable). Theremaining four cows were fed a recovery diet high in fiber (37% NDF),low in PUFA (2.6%), but low in starch degradability (35%).

During the 10-day covariate and 10-day wash out periods, cows were fedthe high fiber, low PUFA, and low starch degradability diet.

Samples and Measurements:

Milk yield, dry matter intake, and feed efficiency were measured dailyfor each animal throughout the covariate, wash out, and samplecollection periods. TMR samples were measured for nutrient composition.During the collection period, milk samples were collected and analyzedevery 3 days. Samples were analyzed for milk component concentrations(milk fat, milk protein, lactose, milk urea nitrogen, somatic cellcounts, and solids) and fatty acid compositions.

Rumen samples were collected and analyzed for microbial communitycomposition and activity every 3 days during the collection period. Therumen was intensively sampled 0, 2, 4, 6, 8, 10, 12, 14, 16, 18, 20, and22 hours after feeding during day 0, day 7, and day 10 of the dietaryMFD. Similarly, the rumen was intensively sampled 0, 2, 4, 6, 8, 10, 12,14, 16, 18, 20, and 22 hours after feeding on day 16 and day 28 duringthe recovery period. Rumen contents were analyzed for pH, acetateconcentration, butyrate concentration, propionate concentration, isoacidconcentration, and long chain and CLA isomer concentrations.

Rumen Sample Preparation and Sequencing:

After collection, rumen samples were centrifuged at 4,000 rpm in a swingbucket centrifuge for 20 minutes at 4° C. The supernatant was decanted,and an aliquot of each rumen content sample (1-2 mg) was added to asterile 1.7 mL tube prefilled with 0.1 mm glass beads. A second aliquotwas collected and stored in an empty, sterile 1.7 mL tube for cellcounting.

Rumen samples with glass beads (1^(st) aliquot) were homogenized withbead beating to lyse microorganisms. DNA and RNA was extracted andpurified from each sample and prepared for sequencing on an IlluminaMiseq. Samples were sequenced using paired-end chemistry, with 300 basepairs sequenced on each end of the library. Rumen samples in empty tubes(2nd aliquot) were stained and put through a flow cytometer to quantifythe number of cells of each microorganism type in each sample.

Sequencing Read Processing and Data Analysis:

Sequencing reads were quality trimmed and processed to identifybacterial species present in the rumen based on a marker gene. Countdatasets and activity datasets were integrated with the sequencing readsto determine the absolute cell numbers of active microbial specieswithin the rumen microbial community. Production characteristics of thecow over time, including pounds of milk produced, were linked to thedistribution of active microorganisms within each sample over the courseof the experiment using mutual information. Maximal informationcoefficient (MIC) scores were calculated between pounds of milk fatproduced and the absolute cell count of each active microorganism.Microorganisms were ranked by MIC score, and microorganisms with thehighest MIC scores were selected as the target species most relevant topounds of milk produced.

Tests cases to determine the impact of count data, activity data, andcount and activity on the final output were run by omitting theappropriate datasets from the sequencing analysis. To assess the impactof using a linear correlation rather than the MIC on target selection,Pearson's coefficients were also calculated for pounds of milk fatproduced as compared to the relative abundance of all microorganisms andthe absolute cell count of active microorganisms.

Results and Discussion

Relative Abundances vs. Absolute Cell Counts

The top 15 target species were identified for the dataset that includedcell count data (absolute cell count, Table 21) and for the dataset thatdid not include cell count data (relative abundance, Table 20) based onMIC scores. Activity data was not used in this analysis in order toisolate the effect of cell count data on final target selection.Ultimately, the top 8 targets were the same between the two datasets. Ofthe remaining 7, 5 strains were present on both lists in varying order.Despite the differences in rank for these 5 strains, the calculated MICscore for each strain was the identical between the two lists. The twostrains present on the absolute cell count list but not the relativeabundance list, ascus_111 and ascus_288, were rank 91 and rank 16,respectively, on the relative abundance list. The two strains present onthe relative abundance list but not the absolute cell count list,ascus_102 and ascus_252, were rank 50 and rank 19, respectively, on theabsolute cell count list.

Integration of cell count data did not always affect the final MIC scoreassigned to each strain. This may be attributed to the fact thatalthough the microbial population did shift within the rumen daily andover the course of the 38-day experiment, it was always within 10⁷-10⁸cells per milliliter. Much larger shifts in population numbers wouldundoubtedly have a broader impact on final MIC scores.

Inactive Species vs. Active Species

In order to assess the impact of filtering strains based on activitydata, target species were identified from a dataset that leveragedrelative abundance with (Table 22) and without (Table 20) activity dataas well as a dataset that leveraged absolute cell counts with (Table 23)and without (Table 21) activity data.

For the relative abundance case, ascus_126, ascus_1366, ascus_1780,ascus_299, ascus 1139, ascus 127, ascus_341, and ascus 252 were deemedtarget strains prior to applying activity data. These eight strains (53%of the initial top 15 targets) fell below rank 15 after integratingactivity data. A similar trend was observed for the absolute cell countcase. Ascus_126, ascus 1366, ascus_1780, ascus_299, ascus 1139,ascus_127, and ascus 341 (46% of the initial top 15 targets) fell belowrank 15 after activity dataset integration.

The activity datasets had a much more severe effect on target rank andselection than the cell count datasets. When integrating these datasetstogether, if a sample is found to be inactive it is essentially changedto a “0” and not considered to be part of the analysis. Because of this,the distribution of points within a sample can become heavily altered orskewed after integration, which in turn greatly impacts the final MICscore and thus the rank order of target microorganisms.

Absolute Cell Counts and Active

Ultimately, the method defined here leverages both cell count data andactivity data to identify microorganisms highly linked to relevantmetadata characteristics. Within the top 15 targets selected using bothmethods (Table 23, Table 20), only 7 strains were found on both lists.Eight strains (53%) were unique to the absolute cell count and activitylist. The top 3 targets on both lists matched in both strain as well asin rank. However, two of the three did not have the same MIC score onboth lists, suggesting that they were influenced by activity datasetintegration but not enough to upset their rank order.

Linear Correlations Vs. Nonparametric Approaches

Pearson's coefficients and MIC scores were calculated between pounds ofmilk fat produced and the absolute cell count of active microorganismswithin each sample (Table 24). Strains were ranked either by MIC (Table24a) or Pearson coefficient (Table 24b) to select target strains mostrelevant to milk fat production. Both MIC score and Pearson coefficientare reported in each case. Six strains were found on both lists, meaningnine (60%) unique strains were identified using the MIC approach. Therank order of strains between lists did not match—the top 3 targetstrains identified by each method were also unique.

Like Pearson coefficients, the MIC score is reported over a range of 0to 1, with 1 suggesting a very tight relationship between the twovariables. Here, the top 15 targets exhibited MIC scores ranging from0.97 to 0.74. The Pearson coefficients for the correlation test case,however, ranged from 0.53 to 0.45—substantially lower than the mutualinformation test case. This discrepancy may be due to the differencesinherent to each analysis method. While correlations are a linearestimate that measures the dispersion of points around a line, mutualinformation leverages probability distributions and measures thesimilarity between two distributions. Over the course of the experiment,the pounds of milk fat produced changed nonlinearly (FIG. 18). Thisparticular function may be better represented and approximated by mutualinformation than correlations. To investigate this, the top targetstrains identified using correlation and mutual information, Ascus 713(FIG. 19) and Ascus_7 (FIG. 20) respectively, were plotted to determinehow well each method predicted relationships between the strains andmilk fat. If two variables exhibit strong correlation, they arerepresented by a line with little to no dispersion of points whenplotted against each other. In FIG. 19, Ascus 713 correlates weakly withmilk fat, as indicated by the broad spread of points. Mutualinformation, again, measures how similar two distributions of pointsare. When Ascus_7 is plotted with milk fat (FIG. 20), it is apparentthat the two point distributions are very similar.

The Present Method in Entirety vs. Conventional Approaches

The conventional approach of analyzing microbial communities relies onthe use of relative abundance data with no incorporation of activityinformation, and ultimately ends with a simple correlation of microbialspecies to metadata (see, e.g., U.S. Pat. No. 9,206,680, which is hereinincorporated by reference in its entirety for all purposes). Here, wehave shown how the incorporation of each dataset incrementallyinfluences the final list of targets. When applied in its entirety, themethod described herein selected a completely different set of targetswhen compared to the conventional method (Table 24a and Table 24c).Ascus_3038, the top target strain selected using the conventionalapproach, was plotted against milk fat to visualize the strength of thecorrelation (FIG. 21). Like the previous example, Ascus 3038 alsoexhibited a weak correlation to milk fat.
